RAID3 - Byte-level Striping + Parity- RAID3 implements classical striping of data (i.e., see the definition of striping above) and partiy is generated and stored on a single drive dedicated for keeping track of the recovery data
- A minimum of three drives is required for implementation (two for the stripe, one for the parity); fault tolerance is a single drive
- Reading performance is excellent and write performance is good (not excellent due to the requirement for parity generation all the time).
- To make things easier to understand, think of RAID3 as RAID0 + Parity
