Parallel ATA stands for Parallel Advanced Technology Attachment. It has been the hard drive interface for desktop PCs for over 15 years. Parallel ATA can be found in desktop PCs, Notebook, Consumer Electronics, and in some servers today. A new interface, Serial ATA, is replacing Parallel ATA technology. Serial ATA leverages the Parallel protocol and enhances it by serially moving data across a thinner, more flexible cable. PATA hard drives, however, still exist in great numbers within the market. Until the complete transition from Parallel to Serial occurs, many PCs will continue to ship and use Parallel ATA hard drives.
