[[RAID]] is an acronym for Redundant Array of Inexpensive Devices - in other words, a way to use multiple physical drives to support a single logical storage volume. There are many different types of RAID, with the most common variants being as follows:

[[RAID0]] - striping without parity (added storage space, decreased reliability) - NOT recommended!
[[RAID1]] - simple mirroring (added access speed and reliability, no change to storage space)
[[RAID3]] - striping with a single parity provider (added storage space, added reliability)
[[RAID5]] - striping with distributed parity across all providers (added storage space, added reliability)

FreeBSD offers solid and reliable kernel-level software RAID at the [[RAID0]], [[RAID1]], and [[RAID3]] levels via the [[geom]] module. Geom [[RAID5]] is available via patches, but has not been implemented in the base system yet - and many argue that [[RAID3]], while not as commonly seen in the outside world, is actually a superior setup anyway. ([[User:Jimbo|Jimbo]] agrees with this statement.)
