Is it worth it?

If you …

  • value your data
  • can’t afford any downtime
  • consider the cost of recovery when you have a drive failure

Yes, it is!

What you describe as RAID 3 is really RAID 4.

RAID 2 = bit level striping
RAID 3 = byte level striping
RAID 4 = block level striping
RAID 5 = block level striping with distributed parity
