Drive checks
Verify CMR or SMR by exact drive model
A drive family name does not guarantee a recording method. Check the exact capacity and model number against the manufacturer source.
Decision 01
Treat product titles as incomplete
Marketplace listings can omit or mix key specifications. Use the manufacturer data sheet, compatibility information, and model number for the final check.
Decision 02
Match the workload
Parity arrays, rebuilds, scrubs, and sustained writes should be considered before mixing storage technologies into a pool.
Decision 03
Record replacement candidates
A plan should keep a short list of compatible replacement drives, warranty details, and an alternative capacity option rather than relying on one listing.
