“Redundant Array of Inexpensive Disks”
Depending on how we configure the array, we can have the
1. data mirrored [RAID 1] (duplicate copies on separate drives)
2. striped [RAID 0] (interleaved across several drives), or
3. parity protected / Stripping with parity [RAID 5](extra data written to identify errors).
These can be used in combination to deliver the balance of performance and reliability that the user requires.
