What to Check Before Buying

CMR vs SMR

For NAS, RAID, or heavy write workloads, insist on CMR. SMR drives are fine for cold backups but stall under sustained writes.

Warranty length

3 years is standard for desktop drives, 5 years for NAS/enterprise lines (WD Red Pro, Seagate IronWolf Pro, Toshiba N300).

Workload rating

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.

Price per TB

The single best value metric. Anything under the current market floor usually means used, shucked, or SMR - check the condition column.

Frequently Asked Questions

What hard drive capacity has the best price per TB right now?

The table above is sorted by price per TB across every capacity we track, so the top row is the current answer. Larger capacities (12TB and up) typically hit the lowest per-TB prices, while drives under 4TB carry a fixed-cost premium.

Should I buy a new or used hard drive?

Used and recertified enterprise drives often cost 30-50% less per TB and were built for 24/7 duty, but usually carry a short seller warranty instead of a 5-year manufacturer one. For irreplaceable data, buy new or buy used only with redundancy (RAID or backups).

CMR or SMR — which should I buy?

For NAS, RAID, or heavy write workloads, insist on CMR. SMR drives are fine for cold backups but stall under sustained writes. Check the specific model before buying, since manufacturers don't always advertise which one a drive uses.
