Question about Value SATA-6 cable

Yes of course, but be careful because you will have to power it with a 15-pin SATA cable

If you want to connect this cable to a sufficiently recent player (DVD, Blu-ray, SD card, etc.) (it must have SATA connectivity, as you can see from the photo and the photo of the cable in question), it should work without any problems :)

Which reader?

Any answer please?
