Seagate Exos Hard Drives

Seagate Exos is Seagate’s datacenter hard drive line, built for servers, storage arrays and large NAS pools that run around the clock. The X series covers high capacity 3.5 inch helium drives, such as the Exos X16 and X18, while the E series covers smaller 3.5 inch drives and 2.5 inch 10K drives for older performance tiers. Most Exos models are sold in both SAS and SATA versions under nearly identical part numbers, so read the full model number carefully: the part number tells you the interface. Exos drives also appear under Dell and HPE part numbers with OEM firmware, and those are included here when the title names the Exos model. When buying used, compare the power-on hours we list for each unit and check the interface against your controller. Every used drive passes SMART health and an extended self-test before it ships.

Seagate Exos: common questions

How do I tell a SAS Exos from a SATA Exos?+

The listing title states the interface, and the part number differs between versions of the same capacity. SAS drives need a SAS HBA, RAID controller or backplane; SATA drives run almost anywhere.

Are Dell or HPE branded Exos drives different?+

The hardware is the same Exos model, but the drive runs OEM firmware and carries the OEM part number. They generally work on standard HBAs and in other servers.

What warranty do these carry?+

Used items carry a 90-day warranty, and certified drive tiers carry up to 2 years; the exact term is on each listing. New sealed items keep the manufacturer warranty.
