DJ800 supports up to 6 SATA devices each with data at transfer rates of 150MB/s. Two Serial ATA ports supported by ICH5R, and four Serial ATA ports supported by Adaptec 8110. Adaptec 8110 also supports RAID configurations. RAID stands for “Redundant Array of Independent De- vices” and provides different levels of safety, redundancy and performance. This chipset supports RAID 0, 1, and 10, which are defined as follows:

drive fails, the other one will be a complete replica and

 

can continue on. Full fail-over
