RAID5 - Block-level Striping + Distributed Parity- Similar to RAID4, RAID5 improves by splitting the parity information across numerous drives in the array (thus removing the write-performance bottleneck)
- Like RAID4, striping is done at a block level (and the stripe size can be adjusted)
- A minimum of three drives is required
- Has a single-drive fault tolerance
- RAID5 offers excellent read performance and good write performance (although improved in comparison to RAID4); should be noted that parity generation can introduce serious system performance degradation issues
