Hardware

Serial ATA

The I/O Hub (82801FBM) provides two Serial ATA150 connections through the J2 connector. Serial ATA is an enhancement of parallel ATA, but is not limited by the traditional restrictions of parallel ATA. Serial ATA has higher performance characteristics with respect to speed and EMV. Serial ATA starts with a transfer rate of 150 Mbytes/s as compared to the legacy Parallel ATA devices that were limited to ATA133 (133MHz) or slower (33/66/100 MHz). In the future, it is hoped that SATA can be expanded up to 600 Mbytes/s to accommodate future advanced developments. Serial ATA is completely protocol and software compatible to parallel ATA.
