Western Digital Serial Ata Cable

The Acronym SATA stands for "Serial Advanced Technology Attachment," and is essentially a transportation system for data to and from a computer hard drive. Older types of hard drives use transport systems (also known as a "bus") that go by names such as Parallel ATA (PATA) and SCSI.

While SCSI is still being used in modern computer systems PATA has all but moved into obsolescence due to the super speed and capabilities of the SATA bus. This article will review the benefits of SATA hard drives over other types and also discusses how SATA cables differ from PATA and SCSI. Other articles on this site discuss related topics and serve as an SATA hard drive buying guide .

Hard Drive Speed Versus SATA Bus Speed

There are several things that go into determining the overall speed of an SATA hard drive. One of these is the speed of the SATA bus, which is currently limited by specification to 300MB/sec. This is more than enough bandwidth for almost any existing application, and far more than the now obsolete PATA specification.
