5.Serial ATA connectors (7-pin PRI_SATA1, SEC_SATA2)

These next generation connectors support the thin Serial ATA cables for primary internal storage devices. The current Serial ATA interface allows up to 150 MB/s data transfer rate, faster than the standard parallel ATA with 133 MB/s (Ultra ATA/133).

Important notes on Serial ATA solution:

•The low-voltage requirement of 500 millivolts (mV) peak-to-peak will effectively minimize, if not totally eliminate, the 5V signalling requirement in the current Parallel ATA interface.

•The Serial ATA cable is smaller and more flexible allowing easier routing inside the chassis. The lower pin count of the Serial ATA cable eliminates the problem caused by the wide, flat ribbon cables of the Parallel ATA interface.
