Every listing we track at this size - 25 product pages, including ones with no current offer. Out-of-stock pages carry specs and in-stock alternatives, never a stale price.
One 6TB 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: 173 camera-days - 8 cameras for 21 days. The arithmetic: 3.2 Mbps ÷ 8 = 0.4 MB/s × 86,400 s = 34.56 GB per camera-day; 6,000 GB ÷ 34.56 = 173 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.
28 in-stock listings out of 28 tracked; the cheapest is the Seagate BarraCuda 6TB ST6000DM003 at $169.99 ($28.33/TB). The table on this page is the live ranking.
Both are in stock: 12 new and 16 recertified or used. The cheapest new is the Seagate BarraCuda 6TB ST6000DM003 at $249.00, the cheapest recertified or used the Seagate BarraCuda 6TB ST6000DM003 at $169.99 - a 32% shelf gap between two different models, not a like-for-like discount. New carries the manufacturer's warranty; recertified a reseller's.
10 of the 28 tracked listings carry a manufacturer-sourced conventional (CMR/ePMR) recording value, including the Seagate SkyHawk 6TB ST6000VX001 and the Seagate SkyHawk 6TB ST6000VX001. 18 are not sourced either way - an unsourced drive is never assumed CMR here.
Seagate, WD, MDD - 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.
