Product overview
The 12TB is the mid-range capacity in Seagate's Exos X16 range, which spans 10TB to 16TB across 4 capacity points. A generation of nearline capacity still filling shelves — common like-for-like replacement.
It attaches over 12Gb/s SAS in the 3.5" LFF form factor. and is dual-ported, so both controllers in a redundant pair keep a path to the drive. The platters spin at 7200 RPM behind a 256 MB cache.

Questions buyers ask about this part
- Will the 12TB Exos X16 fit my server?
- This is a 3.5" LFF part on 12Gb/s SAS. It fits any bay wired for 12Gb/s SAS with dual-port SAS routing. Send us your server model and we will confirm backplane support, firmware level and any bracket or caddy required before you order — that check is part of every order we ship.
- Should I take the 12TB or the 14TB?
- They are the same drive with different capacity: identical 12Gb/s SAS, 3.5" LFF and endurance rating. The 14TB gives you 1.2x the capacity per bay. Where bays are the constraint — a full backplane, or a rack you cannot grow — the larger capacity is usually cheaper per usable terabyte once you count the chassis it saves. Ask us for both on one quote and compare.
- Is this Seagate part genuine, and is the warranty intact?
- Yes. We supply through authorized distribution only, so the part carries the full Seagate manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
- Do you offer volume pricing and accept purchase orders?
- The listed price is per unit and indicative; tiered pricing applies at quantity. We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.
