Faced the problem that the new HDD USB 3.0 is not detected on older computers with USB 2.0 or new computers with USB 3.0, but when using extension cables, due to lack of power. This problem was solved Y- USB cable 3.0.
The cable came in a sealed transparent bag without branding.
In the store, the cable is called like this:
USB 3.0 A Type Male to Micro USB 3.0 + USB 2.0 Male Cable (0.5M)The cable is a micro-USB 3.0 type B cable on one side, on the other side USB 3.0 type A and a parallel piece of USB 2.0 A cable for additional power. All male connectors with golden contacts inside.
On the main cable there is an inscription:
USB 3.0 Cable E119932-T AWM 20276 80°C 30V VW-1 COPARTNER
On the cable supply:
2*AWG VW-1 80°C 300V STONE
Instead of *, there should be an interesting number, which is hidden by an external “braid” near the connector, and you won’t be able to see it without cutting the braid. Although in this case it is not necessary to know it, because. This cable can power any device.
The USB 3.0 cable carries data and power, while the optional USB 2.0 cable only carries power. If there is enough power from one port, then this additional cable can be omitted.
All connectors are marked with a logo corresponding to the USB version, also the USB 3.0 A connector is blue inside and the USB 2.0 connector is black. Very comfortably. The quality of the connectors, plastic braid is excellent.
Length of the main USB 3.0 cable (with connectors): 52 cm.
Additional power cable length: 31 cm.
The main cable is very thick - 6 mm thick, additional - 3 mm. The thickness of the cable is not less than that of the native cable from hard drive Transcend.
The cable has been tested in several places where the supplied cable from the hard drive did not allow the drive to work from one port. The hard drive was connected to a laptop with USB 2.0 and to a computer with USB 3.0, but through extension cables 1.8 m long. In all cases, the drive started up and worked stably.
The cable is of good quality, you can safely take it. Who needs a longer cable, i.e. USB 3.0 Y-Cable for the same price.
Delivery in the store is paid, depending on the weight, but discounts of up to 90% are constantly on it, at the time of purchase the delivery cost $0.34 (with a track number). The cable itself during the delivery fell by $2, I took it for another $5. But in the same
A hard disk is a simple and small "box" in appearance, storing huge amounts of information in the computer of any modern user.
This is exactly what it seems from the outside: a rather uncomplicated little thing. It is rare that when recording, deleting, copying and other actions with files of various importance, they think about the principle of interaction between a hard drive and a computer. And to be even more precise - directly from the very motherboard.
How these components are connected into a single uninterrupted operation, how the hard drive itself is arranged, what connection connectors it has and what each of them is intended for - this is the key information about the storage device that is familiar to everyone.
It is this term that can correctly be called the interaction with the motherboard. The word itself has a much broader meaning. For example, the program interface. In this case, the part that provides a way for a person to interact with the software (a convenient "friendly" design) is meant.
However, it's different. In the case of the HDD and the motherboard, it does not represent 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 loop - 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 hard drive power connector on one end and to the computer power supply itself on the other. And the second of the cables connects the HDD to the motherboard.
The very beginning, after which more advanced HDD interfaces appear. Ancient by today's standards 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, it was worth appearing over time new technology SATA and gain huge popularity in the market as the standard ATA was renamed PATA (Parallel ATA) to avoid confusion.
Extremely slow and very raw in terms of its technical capabilities, this interface in the years of its popularity could pass from 100 to 133 megabytes per second. And then only in theory, because in real practice these figures were even more modest. Of course, newer interfaces and connectors hard drives will show a noticeable lag behind the IDE from modern developments.
Do you think we should not underestimate the attractive sides? Older generations probably remember that the technical capabilities of PATA made it possible to serve two HDDs at once using only one cable connected to the motherboard. But throughput the lines in this case were similarly distributed in half. And this is not even mentioning the width of the wire, which in one way or another prevents the flow of fresh air from the fans in the system unit with its dimensions.
By our time, the IDE is already naturally outdated, both physically and morally. And if until recently this connector was found on motherboards of the lower and middle price segment, now the manufacturers themselves do not see any prospects in it.
For a long time, the IDE has become the most popular interface for working with storage media. But the technologies for data transmission and processing did not stagnate for a long time, soon offering a conceptually new solution. Now it can be found in almost any owner personal computer. And its name is SATA (Serial ATA).
Distinctive features of this interface - parallel low power consumption(compared to IDE), less heating of components. Throughout the history of its popularity, SATA has gone through three phases of revisions:
A couple of updates were also developed for the third revision:
The real figures, of course, clearly differed from the officially declared 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, because they were not originally designed to work at such a read / write speed. Only over time, when the market will gradually be filled with high-speed drives with incredible performance 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 connected hard drives with an IDE connector) with a much compact size and a pleasant appearance. Support for "hot-swapping" HDDs is provided - you can connect / disconnect them without turning off the computer's power (however, you must first activate the AHCI mode in the BIOS).
The convenience of connecting the cable to the connectors has also increased. At the same time, all versions of the interface are backward compatible with each other (hard SATA drive III connects to II on the motherboard without problems, 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 not stand aside either - existing PATA to SATA adapters will save you from the more expensive purchase of a modern HDD or a new motherboard.
But not always a standard hard drive is suitable for the user's tasks. There is a need to store large amounts of data that need to be used in different places and, accordingly, transported. 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 a similar bandwidth.
There is support for "hot-swap" HDD, and the length of the cable itself is increased to two meters.
In the original version, eSATA only allows you to exchange information, without supplying the necessary electricity to the appropriate connector of an external hard drive. This drawback, eliminating 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).
In fact, having become the most common standard for a serial interface for connecting digital equipment, the Universal Serial Bus is known to everyone these days.
Having endured a long history of constant major changes, USB is all about high speed data transfer, powering an unprecedented array of peripherals, and ease and convenience in everyday use.
Developed by companies such as Intel, Microsoft, Phillips, and US Robotics, the interface is the epitome of several technical aspirations:
As is the case with the vast majority of digital technology, the USB hard drive connector for a long time became a completely familiar phenomenon for us. However, in different years of its development, this interface has always demonstrated new heights of speed indicators for reading / writing information.

In addition to this specification, various versions USB implemented and under different types devices. Among the varieties of cables and connectors of this interface, there are:
| USB 2.0 | Standard | ||

USB 3.0 could already offer another new type - C. Cables of this type are symmetrical and are inserted into the corresponding device from any side.
On the other hand, the third revision no longer provides for Mini and Micro "subtypes" of cables for type A.
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 well-known high-speed interface among the masses. Provides serial connection external devices, the supported number of which also includes the 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, preferring SATA or a more advanced USB interface.
This technology acquired its modern technical indicators gradually. So, 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 allowable cable length is 4.5 meters.
The advent of USB 2.0 left the rival behind, allowing data to be exchanged at a speed of 480 megabits per second. However, with the release of the new FireWire 800 (1394b) standard, which made it possible to transmit 800 megabits per second with a maximum cable length at 100 meters, USB 2.0 on the market has been less in demand. This prompted the development of the third version of the serial universal bus, which expanded the data exchange ceiling to 5 Gb / s.
In addition, a distinctive feature of FireWire is its decentralization. The transfer of information via the USB interface necessarily requires a PC. FireWire, on the other hand, allows you to exchange data between devices without necessarily involving a computer in the process.
Intel, together with Apple, showed its vision of which hard drive connector should become the undisputed standard in the future by introducing the Thunderbolt interface (or, according to its old code name, Light Peak) to the world.
Built on PCI-E and DisplayPort architectures, this design allows data, video, audio and power to be transferred through a single port at 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. Even so, Thunderbolt outperformed its closest counterparts, 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 external hard drive connectors, the Thunderbolt. 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.
USB and FireWire compatibility can be achieved with appropriate adapters. This approach will not make them faster in terms of data transfer, since the throughput of both interfaces will still remain unchanged. There is only one advantage here - Thunderbolt will not be a limiting link when similar connection, allowing the use of all technical USB capabilities and firewire.
Another parallel interface for connecting peripherals, which at one point shifted the focus of its development from desktop computers to a wider range of equipment.
The "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 a hard drive connector with stable operation from computers. However, SCSI used a common bus in operation, 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), has already been deprived of its former disadvantage. SAS provides connectivity to devices with a managed SCSI command set over physical interface, which is similar to the same SATA. However, more opportunities allow you to connect not only hard drive connectors, but also many other peripherals (printers, scanners, etc.).
It supports hot-swap devices, bus expanders with the ability to simultaneously connect multiple SAS devices to a single port, and is also backward compatible with SATA.
An interesting way to work with large amounts of data, which is rapidly gaining popularity among modern users.
Or abbreviated NAS is a separate computer with some disk array, which is connected to a network (often a local one) and provides storage and transmission of data among other connected computers.
playing a role network storage, this mini-server is connected to other devices via an ordinary Ethernet cable. Further access to its settings is carried out through any browser with a connection to the network address of the NAS. The available data on it can be used both via an Ethernet cable and using Wi-Fi.
This technology allows you to provide a sufficiently reliable level of information storage and provide convenient easy access to it for trusted persons.
Principle HDD work with a desktop computer is extremely simple and understandable to everyone - in most cases it is required to connect the power connectors of the hard drive to the power supply with the appropriate cable and connect the device to the motherboard in the same way. 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 obliges to take into account several other nuances.
Firstly, to connect storage media directly “inside” the device itself, it should be borne in mind that the HDD form factor should be designated as 2.5 ”
Secondly, in laptop hard the disk is directly connected to the motherboard. Without any additional cables. Simply unscrew the cover for the HDD at the bottom of the previously turned off laptop. It has a rectangular appearance and is usually fastened with a pair of bolts. It is in that capacity that the storage device should be placed.
All laptop hard drive connectors are absolutely identical to their larger "brothers" designed 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-to-USB adapter (there are a huge number of such 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 for power supply. And already with a USB cable, connect this entire structure to a laptop, after which the hard drive will be displayed during operation as another partition.
Perhaps you have an unnecessary hard drive removed from an old computer or laptop that is lying around and gathering dust. If yes, then it will take very little cost to turn it into a removable portable USB stick 2.0 or 3.0. Find out how.
An old disk from a laptop or desktop computer not very suitable for connecting in new equipment - of course, it does not reach the speed and volume of new drives that are connected to the computer. However, you can insert old disk into a special case (adapter) and make a portable USB drive out of it.
A special adapter is not just a piece of plastic - it includes a set of appropriate inputs and is an adapter for USB. Thanks to him, the hard drive, which is designed to be connected to the motherboard through the appropriate connectors (IDE or SATA), can be connected to USB port i.e. make it portable. 
Prices for adapters are quite reasonable, on average about 1000 rubles. The cost also depends on USB interface- an adapter with USB 2.0 will be cheaper than USB 3.0 (difference in data transfer speed).
The adapter itself is not universal and you need to select the appropriate model for a particular drive. You should pay attention to the size of the disk (2.5″ or 3.5″), as well as the cable and power cable (ATA/IDE lub SATA).
Wheels 2.5″ much thinner and mostly laptops are equipped with them. They can be connected via ATA/IDE cable or SATA cable. 
Wheels 3.5″ slightly thicker and usually installed in desktop computer. Also divided into ATA / IDE and SATA. 
Sometimes certain combinations may occur - a new connector can be connected via controller to the "old" motherboard (SATA/IDE). Determining the hard drive is key, because you need to choose the appropriate pocket (adapter) for a given size and interface of the drive.
When choosing an adapter, you should study the properties and find the right model that suits the way the hard drive is connected and its connector. The following is an example of randomly selected USB adapters for various kinds hard drives.
Installing a hard drive in the adapter is not difficult. Depending on the model, it may vary slightly and usually takes no more than a minute. Place the drive into the adapter case, and then connect the wires to the appropriate connectors. 
Depending on the adapter model, interface and hard type The drive may have one or two USB cables on the outside. A USB cable is used to connect to a computer port, and a second cable may be required for additional power.
When connected via a USB cable, the hard drive must be immediately detected by the system and available for data transfer.
