Enterprise Nearline Drive

The Seagate ST1000NX0453 is a 1TB 2.5-inch internal hard drive built for enterprise storage arrays. It uses a SAS 12Gb/s interface and spins at 7200 RPM with 128MB cache. The 15mm z-height fits high-density bays where space and power are constrained.

Suits dense 24×7 arrays.

This drive targets data centres needing high capacity per rack unit with dual-port SAS redundancy. It supports 512e, 4Kn and 512n sector formats for legacy and modern controllers. Builders whose backplanes or host bus adapters only offer SATA 6Gb/s ports cannot use the SAS interface.

SAS 12Gb/s interface decides compatibility

The drive requires a 12Gb/s SAS controller or backplane to operate at its rated speed and provide dual-port failover. If the system only provides SATA connectivity, the drive will not function. Verify the host interface before purchase.

Questions about this item

Will the ST1000NX0453 work in a server that only has 6Gb/s SAS backplanes?

The drive uses a 12Gb/s SAS interface and will negotiate down to 6Gb/s on older backplanes, so it will function at the slower link speed.

How can I confirm the drive is running at 7200 RPM and 12Gb/s after installation?

Check the negotiated link speed and rotational speed in your RAID controller BIOS or OS utilities such as smartctl; they will report 7200 RPM and a 12Gb/s SAS link when operating normally.

Does the open-box ST1000NX0453 include mounting screws or a drive tray for a 2.5" bay?

The drive is supplied as a bare 2.5-inch unit with 15mm z-height; mounting screws, trays or caddies are not included and must be sourced separately.
