Pros & Cons

Pros

✓ Enterprise 2M-hour MTBF rating, built for 24/7 duty cycles
✓ 4TB at 7200RPM with SATA 6Gb/s, not a slower 5400RPM drive
✓ 64MB cache helps sustained sequential reads in RAID arrays
✓ Drops into any SATA host: server, NAS, RAID, PC, Mac, CCTV DVR

Cons

✗ Renewed, not new, so remaining drive hours are unknown at purchase
✗ Bare drive only: no screws, cables, or mounting hardware included
✗ Needs manual formatting before the system will detect it
✗ Sold under Amazon Renewed, not HGST, so warranty terms come from the reseller

SpecPicks Verdict

SpecPicks scored HGST Ultrastar 7K4000 HUS724040ALA640 (0F14688) 4TB 64MB 7200RPM… using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. Amazon Renewed's PC & gaming hardware lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for PC & gaming hardware of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
