Backwards Compatible

One of the good things about the SATA version 3 cables is that they are backwards compatible. So if you have an older SATA hard or optical drive, this cable can let you transfer data at 1.5Gb/s and 3Gb/s, respectively. And if you have connected a SSD and see data transfer speed up to 550 MB/s, you surely have a 6GB/s cable installed.

Right-Angled Connectors

The SATA connectors on a version 3 cable are right-angled (90-degrees). So, this gives you access to connect your drives easily to your motherboard even if there is less space. In older versions of SATA, this feature isn’t available.

Locking Latch

In 6GB/s SATA cables, you will find a locking mechanism either at one or both ends. This metal locking latch ensures proper fitting and secure connection with between motheboard and storage device. Furthermore, it also prevents accidental connection loss which was quite common in older IDE cables.

This locking latch feature is absent in the older versions, SATA 1 and SATA 2.

Durable Construction

As compared to the previous versions, the SATA 6GB/s version comes with a low profile and durable design to fit in toughest spaces in a PC case. Moreover, the clean and sleek design makes this stand against snags and tangles.
