Guides for this capacity: best 16TB hard drive · the HDD price forecast · fill a NAS at today's prices
Every listing we track at this size - 16 product pages, including ones with no current offer. Out-of-stock pages carry specs and in-stock alternatives, never a stale price.
One 16TB 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: 462 camera-days - 8 cameras for 57 days. The arithmetic: 3.2 Mbps ÷ 8 = 0.4 MB/s × 86,400 s = 34.56 GB per camera-day; 16,000 GB ÷ 34.56 = 462 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.
14-20TB drives are the workhorses of enterprise storage arrays. A single 4U JBOD with 60 x 20TB delivers over 1PB of raw storage.
WD Ultrastar DC HC550 (18TB) and HC560 (20TB) use ePMR technology - a CMR variant that is fully RAID compatible despite the different recording method.
Large-capacity nearline drives are ideal for AI training data lakes where sequential read throughput matters more than random IOPS.
$/TB at these capacities has been declining steadily. Wait for quarterly promotions if not urgent - prices can swing 15-20% on enterprise bulk.
15 in-stock listings out of 15 tracked; the cheapest is the Seagate Exos X16 16TB at $469.99 ($29.37/TB). The table on this page is the live ranking.
Both are in stock: 9 new and 6 recertified or used. The cheapest new is the Seagate IronWolf Pro 16TB NAS ST16000NE000 at $699.44, the cheapest recertified or used the Seagate Exos X16 16TB at $469.99 - a 33% 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 15 tracked listings carry a manufacturer-sourced conventional (CMR/ePMR) recording value, including the Seagate Exos X16 16TB and the Seagate SkyHawk AI 16TB ST16000VE002. 11 are not sourced either way - an unsourced drive is never assumed CMR here.
Seagate, WD, Synology - 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.
