2.6 <Serial ATA Interface>
MS-C75 has Four Serial ATA II(SATA Port3/4/5/6) & Two Serial ATA III(SATA Port1/2)
interfaces with RAID function, the transfer rate of the Serial ATA II can be up to 300MB/s
& Serial ATA III can be up to 600MB/s. Please go to http://www.serialata.org/ for more
about Serial ATA technology information. Based on Intel® PC H , it supports Intel® Matrix
Storage Technology with combination of RAID 0,1,5 and 10. The main features of
RAID on Intel® QM77 PCH are listed below:
1. Supports for up to RAID volumes on a single, two-hard drive RAID array.
2. Supports for two, two-hard drive RAID arrays on any of six Serial ATA ports.
3. Supports for Serial ATA ATAPI devices.
4. Supports for RAID spares and automatic rebuild.
5. Supports on RAID arrays, including NCQ and native hot plug.
