The USB cable has two ends - one to connect into the drive, and one to connect into the computer. See in this image the 'A' connector, which will fit into a corresponding rectangular port on your computer. Sometimes these ports are found both on the front and the rear of your computer. Usually it is OK to connect the drive either to the front or to the rear, though if trouble occurs, it is best to connect it to the port on the rear. The new SATA interface combined the SATA and the PCI Express buses. Legacy SATA and PCI express storage devices could now co-exist Three different pins on the connector can work hand-in-hand in parallel to conduct power with varying voltages. Under the Drives branch, press the key to highlight External SATA and press the key. There can be two or four ATA ports on any one motherboard. One cable can connect to two devices at the same time.

Through the SATA interface, the hard drive to the motherboard’s connection speed is very fast and high performance. Version 1 of the SATA cable can transfer 1.5 GB data per second, version 2 can transfer 3 GB data per second, and version 3 can transfer 6 GB data per second.SATA cables are available in different versions; each generation is rated at different speeds and specifications. SATA III is the third generation interface and has a transfer rate of 6Gb/s with a bandwidth throughput of 600MB/s. Their transfer rate was stated at 16.0 Gb/s. As an additional benefit, the choice of PCI Express enables scaling up the performance by using multiple lanes and different versions of PCI Express. (For example: Using two PCI Express 2.0 lanes provides a total bandwidth of 1 GB/s.While using two PCI Express 3.0 lanes provides close to 2 GB/s, equating to effective 1969 MB/s.) One limitation of the eSATA port is that it does not supply power through the same port. You require an external power source for your external device. Press the key once every three seconds while the initial Dell logo is on the screen to enter the BIOS.

( October 2023) SATA 3 interface is quite fast and has super transfer speeds. Can you use a SATA cable on a computer that doesn’t have a SATA connection port? Note: eSATA uses the same technology as that used in the internal Hard Disk Drive (Hard Drive) units of your computer. This saves having to translate data between the interface and the computer. Cables are serial and can be up to 6 and a half feet to 2 meters in length. Unless you are using one of the eSATAp ports, you require an external power source for the storage device. Regular eSATA ports do not supply power. See here a close-up illustration of the adapter fitting into its power connector on the SATA drive. When installing new internal or external hardware on your computer, you need to know which SATA cable connection it needs so that you can connect the correct ports and cables. There are three main types of SATA cable connections for computers: standard two-connection SATA cables, three-connection SATA cables, and eSATA cables.

See here a graphic of the eSATA cable and the port. Please note that the cable's connector and the port look similar to that of a normal Serial ATA connector and port, but they are not intercompatible due to small physical differences. Some SATA drives include a small power adapter that plugs in to the normal power cable inside an older PC or Mac so that it will fit the SATA drive. Note: Confirm that your BIOS is NOT set to SATA legacy mode. eSATA is disabled as default with this setting.

SATA cables are faster than PATA cables with the latest generation operating with a 6Gb/s transfer rate. Which SATA cable generation is used nowadays?

You can only compare up to four products at a time.

USB is the most common connection type for external devices, whether external hard drive, thumb drives, flash drives, printers, cameras, all kinds of other devices. It is extremely easy to use. Whether the computer is powered on or powered off, simply connect the cable to your device and it should be ready to be used less than 30 seconds later (depending on your computer's speed). There is a newer port design eSATAp which not only supplies power, but is also able to be used as a USB port if necessary. The SFF-8639 connector was renamed to a more consumer friendly U.2. This connector is used with some new NVMe SSDs. U.2 utilizes 4 PCIe 3.0 lanes to provide speeds much faster than the SATA interface. Since most motherboards do not have a U.2 connector on them, a M.2 to U.2, or PCIe to U.2 adapter can be used.
