SATA Data Cable
Always use an HP approved SATA 3.0 Gb/s cable as it is fully backwards compatible with the SATA
1.5 Gb/s drives.
Current HP desktop products ship with SATA 3.0 Gb/s hard drives.
SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and
never bend it tighter than a 30 mm (1.18 in) radius.
The SATA data cable is a thin, 7-pin cable designed to transmit data for only a single drive.
