Using Serial ATA RAID This motherboard adopts VIA VT8237R Plus southbridge chipset that supports Serial ATA (SATA) hard disks. You may install two SATA hard disks on the motherboard for storage devices. For optimal performance, please install identical drives of the same model and capacity when creating a RAID set.
1. Introduction RAID Basics RAID (Redundant Array of Independent Disks) is a method of combining two hard disk drives into one logical unit. The advantage of an Array is to provide better performance or data fault tolerance. Fault tolerance is achieved through data redundant operation, where if one drives fails, a mirrored copy of the data can be found on another drive. This can prevent data loss if the operating system fails or hangs. The individual disk drives in an array are called members. The configuration information of each member is recorded in the reserved sector. that identifies the drive as a member. All disk members in a formed disk array are recognized as a single physical drive to the operating system. Hard disk drives can be combined together through a few different methods. The different methods are referred to as different RAID levels. Different RAID levels represent different performance levels, security levels and implementation costs. The RAID levels which the VIA VT8237R Plus SATA RAID Host Controller supports are RAID 0, 1 and JBOD. RAID 0 (Striping) RAID 0 reads and writes sectors of data interleaved between multiple drives. If any disk member fails, it affects the entire array. The disk array data capacity is equal to the number of drive members times the capacity of the smallest member. The striping block size can be set from 4KB to 64KB. RAID 0 does not support fault tolerance.

RAID 1 (Mirroring) RAID 1 writes duplicate data onto a pair of drives and reads both sets of data in parallel. If one of the mirrored drives suffers a mechanical failure or does not respond, the remaining drive will continue to function. Due to redundancy, the drive capacity of the array is the capacity of the smallest drive. Under a RAID 1 setup, an extra drive called the .spare drive. can be attached. Such a drive will be activated to replace a failed drive that is part of a mirrored array. Due to the fault tolerance, if any RAID 1 drive fails, data access will not be affected as long as there are other working drives in the array. JBOD (Spanning) A spanning disk array is equal to the sum of the all drives when the drives used are having different capacities. Spanning stores data onto a drive until it is full, then proceeds to store files onto the next drive in the array. W hen any disk member fails, the failure affects the entire array. JBOD is not really a RAID and does not support fault tolerance.
2. Installing SATA Hard Disks STEP 1: Install the SATA hard disks into the drive bays. STEP 2: Connect one end of the SATA data cable to the motherboard’s primary SATA connector (SATA_1). STEP 3: Connect the other end of the SATA data cable to the master SATA hard disk. STEP 4: Connect one end of the second SATA data cable to the motherboard’s secondary SATA connector (SATA_2). STEP 5: Connect the other end of SATA data cable to the secondary SATA hard disk.
