PATA and SATA hard drives use different power and data cables to connect to the computer. PATA, an older technology used for hard drives, requires a four-pin peripheral power cable to run. SATA hard drives, on the other hand, require a SATA power cable. Power supplies manufactured before 2003 did not include a SATA power cable. However, you can use an adaptor to convert an existing four-pin peripheral power cable to a SATA power cable, allowing you to upgrade nearly any hard disk to SATA.
