How to Know If a SATA Cable is 6GB/s?



SATA cable are the main way through which data is transferred between your motherboard and disk drives. the newer versions of SATA cables can transfer data at a speed of up to 6Gb/s. because SATA cables (old and new) all have similar interface and shape, it makes it a bit harder to figure out which is a 6Gb/s transfer, and which is not. but if you follow this TechSplat guide you will be able to figure it out.

If you have experience changing SATA cables, you can easily distinguish the features that come along with the 6Gb/s cables. Clearly, a 6Gb/s cable can easily be synced with older versions and has a 90 degrees angled connector. Furthermore, it has a simplistic design which makes it easier to install in SFF PC cases.

But if you have never changed any SATA cables in the past, here are some tips that would help you on your task.

SATA cables can be divided into 3 main versions: SATA 1, SATA 2, and SATA 3. Only SATA 3 is capable of transferring data up to 6Gb/s. So in this article, we will discuss the main features of a SATA 3 and help you gain a clear picture.

Backwards Compatible

SATA version 3 cables are backwards compatible, so if you have an older SATA hard or optical drive, this SATA 3 cable will let you transfer data at 1.5Gb/s and 3Bb/s, respectively. And if you have a connected SSD and see data transfer speed up to 550Mb/s, then you surely have a 6Gb/s cable installed.

Right-Angled Connectors

SATA 3 cables are right-angled (90 degrees). This grants you the ability to connect your drives easily to your motherboard even if there is less space. Older versions of SATA do not have this option available.

Locking Latch

in 6Gb/s SATA cables, you will find a locking mechanism either at one or both ends. This metal locking mechanism ensures proper fitting and secure connection between motherboard and storage device. Furthermore, it also prevents accidental connection damage which was very common in older IDE cables.

This locking latch option does not exist in older SATA versions 1, and 2.

Durable Construction

Compared to the previous version, the SATA 6Gb/s version has a low profile and sturdy design to fit in the weirdest angles inside the PC case. Furthermore, the clean and sleek design makes this stand against snags and tangles.


Most SATA 3 cables have a length of up to 1 meter. This grants you the ability to connect your drives from longer distances to your pc even by putting them on the opposite side of the motherboard and curving the cable into the other side to connect it.


Label (on Sata Cable)

New SATA 3 cables come with a proper label on them. However, make sure you buy it from a trusted vendor as many sellers claim to sell SATA 3 cables, but they turn out to be SATA 2 in most cases.

Conclusion on Type of Sata Cable

So, in this article, we have revealed some of the easy steps to find out if you have a 6GB/s SATA cable in your PC or not. To get a high data transfer rate, make sure your motherboard also supports the SATA 3 storage devices. Also, make sure you buy SATA 3 cable from a reliable brand or vendor.
