Guides for this capacity: best 12TB hard drive · the HDD price forecast · fill a NAS at today's prices
Every listing we track at this size - 26 product pages, including ones with no current offer. Out-of-stock pages carry specs and in-stock alternatives, never a stale price.
One 12TB SATA hard drive, in decimal units (1TB = 1,000GB), before file-system and RAID overhead. Each line is a division you can redo; the per-file sizes are our assumptions and say so.
Security cameras, recording continuously: 347 camera-days - 8 cameras for 43 days. The arithmetic: 3.2 Mbps ÷ 8 = 0.4 MB/s × 86,400 s = 34.56 GB per camera-day; 12,000 GB ÷ 34.56 = 347 camera-days. The bitrate is WD's reference figure for one stream (single stream, 1080p, h.265, 25fps), from WD Purple / WD Purple Pro data sheets (footnote 3); the 8-camera count is our example. A camera set to a higher bitrate fills the drive proportionally faster.
6-12TB is the most popular NAS capacity range. IronWolf Pro and Red Pro dominate here with vibration sensors and multi-bay optimization.
IronWolf Pro includes IronWolf Health Management and AgileArray. Ultrastar offers higher workload rating (550 vs 300 TB/yr). Both are CMR and excellent.
8TB+ SATA drives use helium-sealed platters for cooler, quieter operation with lower power draw. Failure rates on helium drives are among the lowest in the industry.
This capacity range often delivers the best $/TB for SATA enterprise storage, especially on 8-12TB Exos and Ultrastar refurb units.
25 in-stock listings out of 25 tracked; the cheapest is the WD Ultrastar 12TB SATA HUH721212ALE601 at $339.49 ($28.29/TB). The table on this page is the live ranking.
Both are in stock: 11 new and 14 recertified or used. The cheapest new is the WD Ultrastar 12TB SATA HUH721212ALE601 at $349.99, the cheapest recertified or used the WD Ultrastar 12TB SATA HUH721212ALE601 at $339.49 - a 3% shelf gap between two different models, not a like-for-like discount. New carries the manufacturer's warranty; recertified a reseller's.
4 of the 25 tracked listings carry a manufacturer-sourced conventional (CMR/ePMR) recording value, including the WD WD Red Pro 12TB WD121KFBX and the WD WD Red Plus 12TB WD120EFGX. 21 are not sourced either way - an unsourced drive is never assumed CMR here.
WD, MDD, Toshiba, Seagate - that is what has live or recently-live listings, not the manufacturers' full line-ups.
Monthly average of every listing tracked that month, new and used together. A level, not a price change: it moves when the mix of listings changes.
