Every listing we track at this size - 9 product pages, including ones with no current offer. Out-of-stock pages carry specs and in-stock alternatives, never a stale price.
3TB SAS vs 3TB SATA → (coming soon)
Small-capacity 10K RPM SAS drives are the cheapest way into low-latency enterprise storage. OEM pulls from Dell and HP often come with caddy trays included.
Dell, HP, and IBM OEM-branded drives are the same Seagate or HGST mechanisms with custom firmware. They work in any SAS controller and are significantly cheaper.
512n drives are universally compatible. 512e drives emulate 512-byte sectors on 4K physical sectors. Both work, but 512n avoids alignment edge cases on older controllers.
10K 2.5" drives suit small-database IOPS workloads. 7.2K 3.5" nearline drives at this capacity are ultra-cheap bulk storage for dev/test or cold data.
11 in-stock listings out of 11 tracked; the cheapest is the HGST HUS724030ALS640 3TB SAS 6G at $45.39 ($15.13/TB). The table on this page is the live ranking.
Both are in stock: 4 new and 7 recertified or used. The cheapest new is the Seagate ST3000NM0023 3TB SAS 6G 7.2K at $69.00, the cheapest recertified or used the HGST HUS724030ALS640 3TB SAS 6G at $45.39 - a 34% shelf gap between two different models, not a like-for-like discount. New carries the manufacturer's warranty; recertified a reseller's.
None of the 11 tracked listings (including the HGST HUS724030ALS640 3TB SAS 6G) has a manufacturer-sourced recording value yet, so this page states none - an unsourced drive is never assumed CMR.
HGST, Seagate, HP, 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.
