Every listing we track at this size - 10 product pages, including ones with no current offer. Out-of-stock pages carry specs and in-stock alternatives, never a stale price.
One 24TB 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: 694 camera-days - 8 cameras for 86 days. The arithmetic: 3.2 Mbps ÷ 8 = 0.4 MB/s × 86,400 s = 34.56 GB per camera-day; 24,000 GB ÷ 34.56 = 694 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.
These pages cover exact model families and recording-technology decisions that a generic capacity table cannot settle.
22TB+ capacity is enabled by HAMR (Heat-Assisted Magnetic Recording) on Seagate Exos and conventional PMR on WD Ultrastar. Both are production-qualified for hyperscale.
These drives are designed for cloud service provider deployments. Minimum order quantities may apply for the best pricing on 30TB+ models.
Highest-capacity drives (30TB+) may have extended lead times. Check stock status carefully - out-of-stock listings can take weeks to fulfill.
A single 2U 12-bay server with 24TB drives = 288TB raw. Plan your density target and compare against multiple smaller drives for redundancy.
7 in-stock listings out of 7 tracked; the cheapest is the WD Ultrastar 24TB SATA WUH722424ALE604 at $779.00 ($32.46/TB). The table on this page is the live ranking.
Both are in stock: 4 new and 3 recertified or used. The cheapest new is the Seagate BarraCuda 24TB ST24000DM001 at $1099.95, the cheapest recertified or used the WD Ultrastar 24TB SATA WUH722424ALE604 at $779.00 - a 29% shelf gap between two different models, not a like-for-like discount. New carries the manufacturer's warranty; recertified a reseller's.
3 of the 7 tracked listings carry a manufacturer-sourced conventional (CMR/ePMR) recording value, including the Seagate Exos X24 24TB and the WD WD Red Pro 24TB WD241KFGX. 4 are not sourced either way - an unsourced drive is never assumed CMR here.
WD, 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.
