12TB SAS vs 12TB SATA → (coming soon)
HGST Ultrastar and Seagate Enterprise Capacity drives in this range have the best published AFR rates. Backblaze data consistently shows HGST leading on reliability.
If your HBA supports 12G, prefer SAS-12G drives for future flexibility. The price premium over SAS-6G is usually small at these capacities.
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.
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.
Absolutely. 12TB SAS drives are the standard capacity for enterprise RAID 6 deployments. A 24-drive array yields over 264TB usable. HGST Ultrastar and Seagate Enterprise Capacity are top picks.
Seagate Exos X, HGST Ultrastar He, and MDD Enterprise are the main options. Helium-sealed drives from HGST offer excellent reliability at these capacities.
New 12TB SAS drives from MDD and Seagate are available with full warranties. Refurbished HGST Ultrastar pulls offer significant savings. For mission-critical storage, buy new. For secondary/backup, refurb is a smart choice.
