1TB SAS vs 1TB 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.
4 in-stock listings out of 4 tracked; the cheapest is the HP ST31000640SS 1TB SAS at $14.99 ($14.99/TB). The table on this page is the live ranking.
All 4 in-stock listings are recertified or used, so the warranty comes from the seller rather than the manufacturer; each row shows its own claim.
None of the 4 tracked listings (including the HP ST31000640SS 1TB SAS) has a manufacturer-sourced recording value yet, so this page states none - an unsourced drive is never assumed CMR.
HP, Seagate, Dell - 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.
