Short for Serial Advanced Technology Attachment, a disk drive implementation that integrates the controller on the disk drive itself. There are several versions of ATA, all developed by the Small Form Factor (SFF) Committee. Often abbreviated SATA or S-ATA, an evolution of the Parallel ATA physical storage interface. Serial ATA is a serial link -- a single cable with a minimum of four wires creates a point-to-point connection between devices. Transfer rates for Serial ATA begin at 150MBps. One of the main design advantages of Serial ATA is that the thinner serial cables facilitate more efficient airflow inside a form factor and also allow for smaller chassis designs. In contrast, IDE cables used in parallel ATA systems are bulkier than Serial ATA cables and can only extend to 40cm long, while Serial ATA cables can extend up to one meter. Serial ATA supports all ATA and ATAPI devices. I run a 36 gig WD Raptor (10,000 rpms) as my system hard drive, and two 200 gig SATA hard drives for storage. SATA's main advantage is slimmer power / data cables, higher data transfer rate and when using a SATA motherboard the ability to daisy chain multiple hard drives without the expense of SCSI drives.
