Hello,

This is a standard SATA cable. Here is an example: Value SATA-3 Kabel (50cm)

However, if you want a cable to connect it to USB, you need another type of product: Delock Konverter USB 3.0 zu SATA 3 Gb/s (Adapter, 0.30m)

Note that for the first cable I already take into account that the case contains a power cable for the hard drive.

If you want more details or if you want a better explanation, just reply to this comment.

Sincerely,
N. Oliveira
