What to Check Before Buying a 4TB Hard Drive
For NAS, RAID, or heavy write workloads, insist on CMR. SMR drives are fine for cold backups but stall under sustained writes.
3 years is standard for desktop drives, 5 years for NAS/enterprise lines (WD Red Pro, Seagate IronWolf Pro, Toshiba N300).
NAS-class drives are rated 180-300 TB/year. Desktop drives (WD Blue, Barracuda) are rated 55 TB/year - fine for a PC, risky in a RAID array.
The single best value metric. Anything under the current market floor usually means used, shucked, or SMR - check the condition column.
