Serial and Parallel ATA Drive Guidelines and Features
4.2 SATA Hard Drive Cables
4.2.1 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 1.5 Gb/s or 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. As
shown in the table, each cable has 3 grounds, and 4 transmit/receive pins.
