RAID
In computing, specifically computer storage, a redundant array of inexpensive (or independent) drives (or disks) (RAID) is an umbrella term for data storage schemes that divide and/or replicate data among multiple hard drives. They offer, depending on the scheme, increased data reliability and/or throughput. The main RAID levels used at all2all are RAID1 and RAID5. For a more complete information about the different RAID levels, please see http://en.wikipedia.org/wiki/RAID0#RAID_0. Note that a RAID system could never replace a good backup strategy.
