TF520 A2+/TF560 A2+ RAID 5: RAID 5 stripes both data and parity information across three or more drives. It writes data and parity blocks across all the drives in the array. Fault tolerance is maintained by ensuring that the parity information for any given block of data is placed on a different drive from those used to store the data itself. Features and Benefits ­ Drives: Minimum 3. ­ Uses: RAID 5 is recommended for transaction processing and general purpose service. ­ Benefits: An ideal combination of good performance, good fault tolerance, and high capacity and storage efficiency. ­ Drawbacks: Individual block data transfer rate same as a single disk. Write performance can be CPU intensive. ­ Fault Tolerance: Yes.
