12TB SAS HDD Buyer's Guide

🏆

HGST & Seagate Reliability

HGST Ultrastar and Seagate Enterprise Capacity drives in this range have the best published AFR rates. Backblaze data consistently shows HGST leading on reliability.

⬆️

SAS-12G Upgrade Path

If your HBA supports 12G, prefer SAS-12G drives for future flexibility. The price premium over SAS-6G is usually small at these capacities.

🔄

Helium vs Air-Filled

8TB and above often use helium-sealed platters (lower friction, cooler, quieter). Helium drives are not refillable - a seal failure means replacement, but failure rates are very low.

📐

3.5" Dominates Here

Almost all drives at this capacity are 3.5" LFF. Ensure your server chassis has LFF bays, or use a 2.5" to 3.5" adapter if needed.

Frequently Asked Questions

12 in-stock listings out of 12 tracked; the cheapest is the HP 12TB SAS 7.2K LFF Enterprise at $359.99 ($30.00/TB). The table on this page is the live ranking.

Both are in stock: 6 new and 6 recertified or used. The cheapest new is the Seagate Exos 12TB SAS 12G 7200RPM at $529.35, the cheapest recertified or used the HP 12TB SAS 7.2K LFF Enterprise at $359.99 - a 32% shelf gap between two different models, not a like-for-like discount. New carries the manufacturer's warranty; recertified a reseller's.

None of the 12 tracked listings (including the HP 12TB SAS 7.2K LFF Enterprise) has a manufacturer-sourced recording value yet, so this page states none - an unsourced drive is never assumed CMR.

HP, WD, HGST, Seagate, Synology - that is what has live or recently-live listings, not the manufacturers' full line-ups.
