RAID balances capacity, performance and disk-failure tolerance; RAID is not backup and should be evaluated together with workload IOPS and latency requirements.
Why This Topic Matters
RAID balances capacity, performance and disk-failure tolerance; RAID is not backup and should be evaluated together with workload IOPS and latency requirements.
Key Decision Points
Do not choose RAID only by usable capacity.
Account for rebuild time and drive size.
Evaluate parity overhead for write-heavy workloads.
Do not use RAID as a substitute for independent backup.
