3.3 SATA (Serial ATA Interface)
Serial ATA is a serial interface for connecting storage devices (mainly hard disks). SATA
uses a point-to-point serial connection between the system and the storage device. The
first-generation SATA provides a maximum data transfer rate of 1.5Gb/s per port. The
second generation SATA 3Gb/s provides transfer rate of up to 3Gb/s per port while the
third generation SATA 6Gb/s provides transfer rate of up to 6Gb/s. Serial ATA is
completely software transparent to the IDE interface while providing a lower pin count and
higher performance.
3.3.1 Signal Description
All COM Express modules provide up to four Serial ATA channels, each with a receive
and transmit differential signal pair. The appropriate signals can be found on the COM
Express module connector row A and row B.
