Intel Matrix RAID

From Wikipedia, the free encyclopedia

Intel Matrix RAID is a RAID layout employing two physical hard disks, in which part of each disk is assigned to a RAID 0 array, and the other part to a RAID 1 array. Traditionally, other inexpensive RAID products only allow a disk to participate in a single RAID array.

It first appeared in the Intel ICH6R RAID BIOS. Intel Matrix RAID is not a new RAID level.

Intel's recommended setup is to put the operating system, critical application programs and data on the RAID 1 volume. The thinking being that protection from losing the configured OS, programs and data is more important than a performance increase. The RAID 0 volume in Matrix RAID is promoted mostly for working with large files, such as videos during editing, and for non-critical files where fast storage will increase performance (swap files, for example).
