Pinout of computer power connectors. Wiring diagram for SATA - power connector and hard drive power connector - SATA Hard drive sata connectors

A hard drive is a simple and small “box” in appearance that stores huge amounts of information in the computer of any modern user.

This is exactly what it seems like from the outside: a fairly uncomplicated little thing. Rarely does anyone, when recording, deleting, copying and other actions with files of varying importance, think about the principle of interaction between the hard drive and the computer. And to be even more precise - directly with the motherboard itself.

How these components are connected into a single uninterrupted operation, how the hard drive itself is designed, what connection connectors it has and what each of them is intended for - this is key information about the data storage device that is familiar to everyone.

HDD interface

This is the term that can correctly be used to describe interaction with the motherboard. The word itself has a much broader meaning. For example, the program interface. In this case, we mean the part that provides a way for a person to interact with the software (convenient “friendly” design).

However, there is discord. In the case of the HDD and motherboard, it does not present a pleasant graphic design for the user, but a set of special lines and data transfer protocols. These components are connected to each other using a cable - a cable with inputs at both ends. They are designed to connect to ports on the hard drive and motherboard.

In other words, the entire interface on these devices is two cables. One is connected to the power connector of the hard drive at one end and to the computer’s power supply itself at the other. And the second of the cables connects the HDD to the motherboard.

How a hard drive was connected in the old days - the IDE connector and other relics of the past

The very beginning, after which more advanced HDD interfaces appear. Ancient by today's standards, it appeared on the market around the 80s of the last century. IDE literally means “embedded controller”.

Being a parallel data interface, it is also commonly called ATA - However, as soon as the new SATA technology appeared over time and gained enormous popularity in the market, the standard ATA was renamed PATA (Parallel ATA) to avoid confusion.

Extremely slow and completely raw in its technical capabilities, this interface during the years of its popularity could transfer from 100 to 133 megabytes per second. And then only in theory, because in real practice these indicators were even more modest. Of course, newer interfaces and hard drive connectors will show a noticeable lag between the IDE and modern developments.

Do you think we shouldn’t downplay the attractive sides? Older generations probably remember that the technical capabilities of PATA made it possible to service two HDDs at once using only one cable connected to the motherboard. But the line capacity in this case was similarly distributed in half. And this is not to mention the width of the wire, which somehow, due to its dimensions, impedes the flow of fresh air from the fans in the system unit.

By now, the IDE is naturally outdated, both physically and morally. And if until recently this connector was found on motherboards in the low and mid-price segment, now the manufacturers themselves do not see any prospects in it.

Everyone's favorite SATA

For a long time, IDE became the most popular interface for working with information storage devices. But data transmission and processing technologies did not stagnate for long, soon offering a conceptually new solution. Now it can be found in almost any owner of a personal computer. And its name is SATA (Serial ATA).

Distinctive features of this interface are parallel low power consumption (compared to IDE), less heating of components. Throughout the history of its popularity, SATA has undergone development in three stages of revisions:

1. SATA I - 150 Mb/s.
2. SATA II - 300 MB/s.
3. SATA III - 600 MB/s.

A couple of updates were also developed for the third revision:

• 3.1 - more advanced throughput, but still limited to 600 MB/s.
• 3.2 with the SATA Express specification - a successfully implemented merger of SATA and PCI-Express devices, which made it possible to increase the read/write speed of the interface to 1969 MB/s. Roughly speaking, the technology is an “adapter” that converts the normal SATA mode to a higher speed one, which is what the PCI connector lines have.

The real indicators, of course, clearly differed from the officially announced ones. First of all, this is due to the excess bandwidth of the interface - for many modern drives the same 600 MB/s is unnecessary, since they were not originally designed to operate at such read/write speeds. Only over time, when the market gradually becomes filled with high-speed drives with operating speeds that are incredible for today, will the technical potential of SATA be fully utilized.

Finally, many physical aspects have been improved. SATA is designed to use longer cables (1 meter versus 46 centimeters that were used to connect hard drives with an IDE connector) with a much more compact size and pleasant appearance. Support for “hot-swap” HDDs is provided - you can connect/disconnect them without turning off the computer’s power (however, you still need to first activate the AHCI mode in the BIOS).

The convenience of connecting the cable to the connectors has also increased. Moreover, all versions of the interface are backward compatible with each other (a SATA III hard drive connects without problems to II on the motherboard, SATA I to SATA II, etc.). The only caveat is that the maximum speed of working with data will be limited by the “oldest” link.

Owners of old devices will also not be left out - existing PATA to SATA adapters will often save you from the more expensive purchase of a modern HDD or a new motherboard.

External SATA

But a standard hard drive is not always suitable for the user’s tasks. There is a need to store large volumes of data that require use in different places and, accordingly, transportation. For such cases, when you have to work with one drive not only at home, external hard drives have been developed. Due to the specifics of their device, they require a completely different connection interface.

This is another type of SATA, created for external hard drive connectors, with the external prefix. Physically, this interface is not compatible with standard SATA ports, but it has similar throughput.

There is support for hot-swap HDD, and the length of the cable itself has been increased to two meters.

In its original form, eSATA only allows for the exchange of information, without supplying the necessary electricity to the corresponding connector of the external hard drive. This drawback, which eliminates the need to use two cables at once for connection, was corrected with the advent of the Power eSATA modification, combining eSATA technologies (responsible for data transfer) with USB (responsible for power).

Universal Serial Bus

In fact, having become the most common serial interface standard for connecting digital equipment, Universal Serial Bus is known to everyone these days.

Having endured a long history of constant major changes, USB stands for high data transfer speeds, power for an unprecedented variety of peripheral devices, and ease and convenience for everyday use.

Developed by companies such as Intel, Microsoft, Phillips and US Robotics, the interface became the embodiment of several technical aspirations:

• Expanding the functionality of computers. Standard peripherals before the advent of USB were quite limited in variety and each type required a separate port (PS/2, port for connecting a joystick, SCSI, etc.). With the advent of USB, it was thought that it would become a single universal replacement, significantly simplifying the interaction of devices with a computer. Moreover, this development, new for its time, was also supposed to stimulate the emergence of non-traditional peripheral devices.
• Provide connection of mobile phones to computers. The widespread trend in those years for the transition of mobile networks to digital voice transmission revealed that none of the interfaces developed then could provide data and voice transmission from the phone.
• Inventing a convenient "plug and play" principle, suitable for "hot plugging".

As is the case with the vast majority of digital equipment, the USB connector for a hard drive has become a completely familiar phenomenon for a long time. However, in different years of its development, this interface has always demonstrated new peaks in speed indicators for reading/writing information.

In addition to this specification, different versions of USB are implemented for different types of devices. Among the varieties of cables and connectors of this interface are:

USB 3.0 could already offer another new type - C. Cables of this type are symmetrical and are inserted into the corresponding device from either side.

On the other hand, the third revision no longer provides for Mini and Micro “subtypes” of cables for type A.

Alternative FireWire

For all their popularity, eSATA and USB are not all options for how to connect an external hard drive connector to a computer.

FireWire is a slightly less known high-speed interface among the masses. Provides serial connection of external devices, the supported number of which also includes HDD.

Its property of isochronous data transmission has mainly found its application in multimedia technology (video cameras, DVD players, digital audio equipment). Hard drives are connected to them much less often, giving preference to SATA or a more advanced USB interface.

This technology acquired its modern technical characteristics gradually. Thus, the original version of FireWire 400 (1394a) was faster than its then main competitor USB 1.0 - 400 megabits per second versus 12. The maximum permissible cable length was 4.5 meters.

The arrival of USB 2.0 left its rival behind, allowing data exchange at a speed of 480 megabits per second. However, with the release of the new FireWire 800 (1394b) standard, which allowed transmission of 800 megabits per second with a maximum cable length of 100 meters, USB 2.0 was less in demand on the market. This prompted the development of the third version of the serial universal bus, which expanded the data exchange ceiling to 5 Gbit/s.

In addition, a distinctive feature of FireWire is its decentralization. Transferring information via a USB interface requires a PC. FireWire allows you to exchange data between devices without necessarily involving a computer in the process.

Thunderbolt

Intel, together with Apple, showed its vision of which hard drive connector should become an unconditional standard in the future by introducing the Thunderbolt interface to the world (or, according to its old code name, Light Peak).

Built on PCI-E and DisplayPort architectures, this design allows you to transfer data, video, audio and power through a single port with truly impressive speeds of up to 10 Gb/s. In real tests, this figure was a little more modest and reached a maximum of 8 Gb/s. Nevertheless, even so, Thunderbolt has overtaken its closest analogs FireWire 800 and USB 3.0, not to mention eSATA.

But this promising idea of ​​a single port and connector has not yet received such mass distribution. Although some manufacturers today successfully integrate connectors for external hard drives, the Thunderbolt interface. On the other hand, the price for the technical capabilities of the technology is also relatively high, which is why this development is found mainly among expensive devices.

Compatibility with USB and FireWire can be achieved using appropriate adapters. This approach will not make them faster in terms of data transfer, since the throughput of both interfaces will still remain the same. There is only one advantage here - Thunderbolt will not be the limiting link with such a connection, allowing you to use all the technical capabilities of USB and FireWire.

SCSI and SAS - something that not everyone has heard of

Another parallel interface for connecting peripheral devices, which at one point shifted the focus of its development from desktop computers to a wider range of equipment.

"Small Computer System Interface" was developed a little earlier than SATA II. By the time the latter was released, both interfaces were almost identical in their properties to each other, capable of providing the hard drive connector with stable operation from computers. However, SCSI used a common bus, which is why only one of the connected devices could work with the controller.

Further refinement of the technology, which acquired the new name SAS (Serial Attached SCSI), was already devoid of its previous drawback. SAS provides connection of devices with a set of managed SCSI commands via a physical interface, which is similar to SATA. However, broader capabilities allow you to connect not only hard drive connectors, but also many other peripherals (printers, scanners, etc.).

Supports hot-swappable devices, bus expanders with the ability to simultaneously connect multiple SAS devices to one port, and is also backward compatible with SATA.

Prospects for NAS

An interesting way to work with large volumes of data, rapidly gaining popularity among modern users.

Or, abbreviated as NAS, they are a separate computer with some disk array, which is connected to a network (often to a local one) and provides storage and transmission of data among other connected computers.

Acting as a network storage device, this mini-server is connected to other devices via an ordinary Ethernet cable. Further access to its settings is provided through any browser connected to the NAS network address. The available data on it can be used both via an Ethernet cable and via Wi-Fi.

This technology makes it possible to provide a fairly reliable level of information storage and provide convenient, easy access to it for trusted persons.

Features of connecting hard drives to laptops

The principle of operation of an HDD with a desktop computer is extremely simple and understandable to everyone - in most cases, you need to connect the power connectors of the hard drive with the power supply using the appropriate cable and connect the device to the motherboard in the same way. When using external drives, you can generally get by with just one cable (Power eSATA, Thunderbolt).

But how to properly use laptop hard drive connectors? After all, a different design requires taking into account slightly different nuances.

Firstly, to connect information storage devices directly “inside” the device itself, it should be taken into account that the HDD form factor must be designated as 2.5”

Secondly, in a laptop the hard drive is connected directly to the motherboard. Without any additional cables. Simply unscrew the HDD cover on the bottom of the previously switched off laptop. It has a rectangular appearance and is usually secured with a pair of bolts. It is in that container that the storage device should be placed.

All laptop hard drive connectors are absolutely identical to their larger “brothers” intended for PCs.

Another connection option is to use an adapter. For example, a SATA III drive can be connected to USB ports installed on a laptop using a SATA-USB adapter (there are a huge variety of similar devices on the market for a variety of interfaces).

You just need to connect the HDD to the adapter. It, in turn, is connected to a 220V outlet to supply power. And use a USB cable to connect this entire structure to the laptop, after which the hard drive will be displayed as another partition during operation.

Have you bought a brand new hard drive for your computer and don’t know how to connect it?! In this article I will try to talk about this in detail and in an accessible way.

To begin with, it should be noted that the hard drive is connected to the motherboard either through the IDE interface or through the SATA interface. The IDE interface is currently considered obsolete, as it was popular back in the 90s of the last century, and new hard drives are no longer equipped with it. The SATA interface is found in all computers that have been produced since approximately 2009. We will consider connecting a hard drive with both interfaces.

Connecting a hard drive via SATA interface

Disconnect the system unit from the network and remove the side panel. At the front of the system unit there are compartments for devices. Optical drives for CD/DVD and Blu-Ray are usually installed in the upper compartments, while the lower compartments are intended for installing hard drives. If your system unit does not have the compartments shown in the figure, you can install the hard drive in the upper compartment.

We install the hard drive in a free cell so that the connectors face inside the system unit, and fasten it to the case with screws: two screws on one side and two on the other.

This completes the installation of the hard drive, check that it is not loose in the cell.

Now you can connect the hard drive to the motherboard.

If you purchased a hard drive with a SATA interface, then the drive itself has two connectors: the shorter one is responsible for transferring data from the motherboard, the longer one is for power. Additionally, the hard drive may have another connector; it is useful for supplying power via the IDE interface.

The data cable has identical plugs at both ends.

We connect one end of the cable to the SATA data connector on the hard drive.

The data cable plug can be either straight or L-shaped. You don’t have to worry about the correct connection; you simply won’t be able to plug the cable into the wrong connector or the wrong side.

We connect the other end of the cable to the connector on the motherboard, usually they are bright in color.

If the motherboard does not have a SATA connector, you need to buy a SATA controller. It looks like a board and is installed in the system unit in a PCI slot.

We are done connecting the data cable. Now we connect the power cable to the corresponding connector of the hard drive.

If your power supply does not have connectors for SATA devices, and the hard drive does not have an additional power connector for the IDE interface, use an IDE/SATA power adapter. Connect the IDE plug to the power supply, the SATA plug to the hard drive.

That's all, we connected a hard drive with a SATA interface.

Connecting a hard drive via the IDE interface

We install the hard drive into the system unit in the same way as described in the paragraph above.

Now you need to set the hard drive operating mode: Master or Slave. If you are installing one hard drive, select Master mode. To do this, you need to place the jumper in the desired position.

The IDE connectors on the motherboard look like this. Next to each of them there is a designation: either IDE 0 – primary, or IDE 1 – secondary. Since we are connecting one hard drive, we will use the primary connector.

That's all, the hard drive is now connected.

I think now, using the information from this article, you can P connect the hard drive to the computer.

SATA (English: Serial ATA)- serial interface for data exchange with information storage devices. SATA is a development of the parallel interface, which after the advent of SATA was renamed PATA (Parallel ATA). - data cable connector. Hard drive data cable connector -

Description SATA

SATA uses a 7-pin connector instead of PATA's 40-pin connector. The SATA cable has a smaller area, due to which the resistance to air blowing through the computer components is reduced, and wiring inside the system unit is simplified.

Due to its shape, the SATA cable is more resistant to multiple connections. The SATA power cord is also designed to accommodate multiple connections. The SATA power connector supplies 3 supply voltages: +12 V, +5 V and +3.3 V; however, modern devices can operate without +3.3 V, which makes it possible to use a passive adapter from a standard IDE to SATA power connector. A number of SATA devices come with two power connectors: SATA and Molex.

The SATA standard abandoned the traditional PATA connection of two devices per cable; each device is assigned a separate cable, which eliminates the problem of the impossibility of simultaneous operation of devices located on the same cable (and the delays that arise from this), reduces possible problems during assembly (there is no problem of conflict between Slave/Master devices for SATA), eliminates the possibility of errors when using non-terminated PATA- loops.

The SATA standard supports the command queuing function (NCQ, starting with SATA Revision 2.x).

The SATA standard does not provide for hot-swapping of the active device (used by the Operating System) (up to SATA Revision 3.x), additionally connected drives must be disconnected gradually - power, cable, and connected in the reverse order - cable, power.

SATA connectors

SATA devices use two connectors: 7-pin (data bus connection) and 15-pin (power connection). The SATA standard provides the ability to use a standard 4-pin Molex connector instead of a 15-pin power connector. Using both types of power connectors at the same time may damage the device.

The SATA interface has two data transfer channels, from controller to device and from device to controller. LVDS technology is used to transmit the signal; the wires of each pair are shielded twisted pairs.

There is also a 13-pin combined SATA connector used in servers, mobile and portable devices for slim CD/DVD drives. Devices are connected using a SATA Slimline ALL-in-One Cable. It consists of a combined connector of a 7-pin connector for connecting the data bus and a 6-pin connector for connecting the device’s power supply. In addition, to connect to these devices, servers use a special adapter.

Using http://ru.wikipedia.org/wiki/SATA

The most interesting comments on the colors of the SATA power connector cable:

RU2012:"Adapters are available to convert a 4-pin Molex connector to a SATA power connector. However, since 4-pin Molex connectors do not provide 3.3 V, these adapters only provide 5 V and 12 V power and leave the 3.3 V lines disabled. This does not allow the use of such adapters with drives that require 3.3 V power - orange wire.

Recognizing this, hard drive manufacturers have largely left support for the 3.3V orange power cable option in their storage devices - power lines are not used in most devices.

HOWEVER, WITHOUT 3.3V POWER (orange wire), the SATA DEVICE MAY NOT BE ABLE TO HOT PLUG THE DISK..." - http://en.wikipedia.org/wiki/Serial_ATA

SATA is an interface used for communication between the motherboard and the HDD. The technology is based on a rules protocol that determines how bits will be transferred in the controller that handles the transmission and signal lines on the cable. The interface is serial, which means that data is transferred bit by bit.

The development of the technology began back in 2000, by the best companies in the IT field. The connector began to be integrated into motherboards in 2003.

SATA – translated as consistent application of the latest technologies. Stands for Serial Advanced Technology Attachment. The key word here is Serial, which means “serial”, which is how the interface differs from its predecessor PATA.

IDE (aka PATA) uses parallel data transfer, which is much inferior in speed to the newer interface. In addition, IDE uses a 40-pin cable, which makes it difficult for air to circulate inside the PC and increases the temperature.

Cables and connectors

To connect a hard drive using Serial ATA you will need two cables.

The first cable is used for data transmission and has 7 contacts. The second SATA cable is for power supply and connects directly to the power supply via a 4-pin MOLEX connector. The voltage that passes through the power cable is 3, 3.5 and 12 V, while the current is 4.5 A.

In order not to create sudden jumps in the transition from one interface to another, in terms of power supply, many HDDs have the old 4-pin connector.

Newer HDDs use only a 15-pin SATA connector.

SATA and IDE interface

Types of SATA

Since its release (2003), the development of the technology has not stood still and faster and more stable versions have been released. At the moment, there are 6 main versions that are widely popular and in demand.

Sata

The first model is currently quite difficult to find on PCs. Operates on frequency 1.5 GHz and has a capacity of 150 Mb/s, which does not greatly exceed the throughput of Ultra ATA. The main advantage over the previous interface is the serial bus, which provides higher data transfer speeds.

Sata 2

SATA 2 came out the next year after the first version was released. The bus frequency has become 3 GHz, and the throughput 300 Mb/s. I used a chipset from NVIDIA called nForce 4. Visually it looks like the first version.

Sata 3

The first variation of version 3 appeared in 2008. Data transfer rate 600 Mb/s.

Version 3.1 improved performance with SSDs and reduced overall power consumption for a system that includes multiple devices.

Version 3.2 has a distinctive feature - it is a merger of PCI Express and Serial ATA called SATA Express. The main one is PCI, but is still compatible with Serial ATA in software. Has a capacity of 1969 Mb/s.

Esata

This technology is used to connect external devices that use the " Hot Swap" The connectors have been changed and are now incompatible with standard Serial ATA, although they are identical in terms of signal. Also, the connectors have become more durable, which allows for a greater number of connections/disconnections of devices before failure. Two cables are used, one for data transmission, the other for power.

Esata connector

Difference between Esata and SATA

Power eSATA

Power eSATA (eSATAp) - specially designed to eliminate the need for two cables when connecting. This interface transmits data and power over a single cable, making it easier to use.

Msata

An interface that is used in netbooks and ultrabooks, replacing the more bulky connector of its predecessor. Bandwidth 6 Gbps.

SAS

An interface for connecting devices via a physical channel, analogous to Serial ATA, that are controlled using the SCSI command set. This makes it possible connect any devices, which use the SCSI command set for management, this is also facilitated by backward compatibility with Serial ATA. If we compare these two interfaces, the SAS topology is at a more advanced level, which allows one device to be connected in parallel via two or more channels. The first revisions of SAS and Serial ATA 2 were listed as synonyms, but over time the creators decided that using SCSI in a PC was inappropriate and separated them.

What's happened

This is a technology combining PCI Express and SATA. On the motherboard it looks like two adjacent SATA ports, which allows you to connect both devices using previous interfaces and a newer one. Bandwidth 8 Gb/s when connecting one connector and 16 Gb/s when connecting two connectors at once.

Sata Express connectors

Sata Express cable

Differences and compatibility

All versions are backward compatible with each other. Those. If you have Serial ATA 3, the user can easily connect a device using version 2. And so with all versions.

The throughput of version 3 is twice as high as that of version 2 and is 6 Gbps. Compared to the previous one it was improved power management.

How to find out which SATA is on the motherboard

The user can find out which Serial ATA connector is installed on the motherboard in several ways. For owners of desktop PCs, the first method will be the most relevant.

You need to remove the side cover of the system unit to get to the motherboard. If you have a laptop you will have to completely disassemble it. It is not recommended for an inexperienced user to do this. After you get to the motherboard you should find connector with inscriptionSATA or you can simply track the cable that goes from the HDD to the motherboard. Near this connector on the motherboard it will be written SATA. 6 Gb/s is the third revision, and 3 Gb/s is the second.

If it is not possible to disassemble it, but you need to find out the Serial ATA connector, you can use programs. You need to download the HWiNFO program, install it and open it.

In the main window select Bus – Pci Bus and look on the right side of the window which Serial ATA ports are present on the motherboard.

SATA(Serial -ATA, SerialAdvancedTechnologyAttachment) is a type of computer bus interface designed for connecting devices, optical drives, and others.

Was developed and presented in 2003 year, as a replacement for the now outdated interfaceATA(AT Attachment ), also known asIDE. Later, ATAwas renamed toPATA(Parallel ATA , for better recognition and avoiding confusion.

An organization calledSATA-IO (Sata International Organization ), which is responsible for the development, support, and publication of new specifications for bothSATA, and for SAS (Serial Attached SCSI ).

Advantagesnew interface compared to the old one were like physical:reduced dimensions of connectors, cables and fewer contact pins ( 7 vs 40); so and technical: native support for hot replacements"(replacement of inactive device), faster data transfer at higher speeds, increased queue efficiency I/O commands (I O). Later, with the advent of the regime, support for technology appeared.

Theoretically, a serial port is slower than a parallel one, but the speed increase was achieved thanks to high operating frequency. The frequency was increased due to the absence of the need for data synchronization, as well as greater cable security from interference (thicker conductor, less interference).

IN 2008 year, more 90% new desktop computers were used to connect peripheralsSATAconnector PATA can still be purchased, but they are sold only to maintain compatibility with older drives and motherboards.

AuditsSATA :

SATA 1. x

The first revision of the interface provides for the frequency of operation 1.5 GHz, which provides bandwidth 1.5 Gbps. Near 20% is taken away for the needs of the type coding system 8 b 10 b, where in every 10 bits more is being invested 2 bits service information. So the maximum speed is 1.2 Gbit/s (150 Mb/s). It's quite a bit faster than the fastestPATA/133 , but much better performance is achieved in the modeAHCIwhere support worksNCQ (Native Command Queuing ). This significantly improves performance in multi-threaded tasks, but not all controllers support AHCI on the first version SATA.

SATA 2. x

The operating frequency has been increased to 3.0 GHz, which increased the throughput to 3.0 Gbps. The effective throughput is equal to 2.4Gbps (300MB/ c), that is, 2 times higher than that ofSATA 1 . Compatibility preserved between the first and second revisions. The interface cables were also kept the same and fully compatible between themselves.

SATA 3.0

In July 2008, SATA-IO submitted specificationsSATA 3.0 , with capacity 6 Gbit / With. Full 3.0 the standard was released in May 2009.

The effective throughput was 600Mb/s, and the operating frequency 6.0GHz(that is, only the frequency is raised). Compatibility preserved both in the data transmission method and in connectors and wires; Improved power management.

The main application where such bandwidth was required wasSSD (solid state) drives. For hard drives, such bandwidth was not required. The benefit for them was the higher data transfer speed from cache ( DRAM - cache) disk memory.

SATA 3.1

Changes:

• · Appeared mSATA, a similar (and compatible) connector for solid state drives and laptop devices, combined with supply line low power.
• Optical drives supporting the standard are larger do not consume energy(completely) in mode just me.
• · Added hardware queue command, improving performance and durability SSD.
• · Hardware features identification, defining possibilities devices.
• ·Advanced nutrition management, allowing devices connected via SATA 3.1 to consume less energy.

mSATA

– PCI— e like interface introduced in September 2009 of the year. Designed for miniature devices(solid state drives, portable hard drives). It is also planned to be used in portable devices such as laptops and others.. Devices with this interface may have very miniature sizes, similar to expansion cards for laptops (for example).

Exist adapters Pata— Sata , Sata— Pata.

They allow you to connect devices with different interfaces that emulated by a special controller on the adapter. The vast majority of adapters require additional food from the power supply (usually type " molex" or 5V drive connector).
