Definitions for "Serial ATA"
This is a specification that for consumer hard drive connections that boosts the data transfer rate up to 1.5Gbps, about three times the speed of UDMA/66. In addition, it changes IDE/ATA from a parallel interface requiring 40 separate wires to connect components, to a serial interface requiring only six wires. 2x and 4x versions of Serial ATA double and triple the speed of Serial ATA.
a high performance interface for IDE storage devices, and is the evolutionary replacement for the longstanding ATA physical storage interface
