Guide to RAID Configurations

This motherboard adopts MCP-RAID south bridge chipset that

integrates RAID controller supporting RAID 0 / RAID 1 / RAID 0+1 /

JBOD function with two independent Serial ATA (SATA) channels.

This section will introduce the basic knowledge of RAID, and the

guide to configure RAID 0, RAID 1, RAID 0+1, and JBOD settings.

RAID

The term "RAID" stands for "Redundant Array of Independent

Disks", which is a method combining two or more hard disk drives

into one logical unit. For optimal performance, please install

identical drives of the same model and capacity when creating a

RAID set.

RAID 0 (Data Striping)

RAID 0 is called data striping that optimizes two identical hard disk

drives to read and write data in parallel, interleaved stacks. It will

improve data access and storage since it will double the data

transfer rate of a single disk alone while the two hard disks

perform the same work as a single drive but at a sustained data

transfer rate.

WARNING!!

Although RAID 0 function can improve the access performance, it

does not provide any fault tolerance. Hot-Plug any HDDs of the

RAID 0 Disk will cause data damage or data loss.
