Enterprise SAS Storage Drive

The DELL ST91000640SS is a 1TB 2.5 inch hard drive built for enterprise SAS environments. It operates at 7200 RPM with a 64 MB cache to support sustained workloads in compatible servers and arrays.

Suited for SAS bays only

This drive fits 2.5 inch SAS drive bays and backplanes that accept the Constellation product line. It will not function on interfaces other than SAS, so systems without a SAS controller or backplane cannot use it.

64 MB cache specification

The on-board 64 MB cache is the key figure that determines suitability for write-heavy enterprise tasks. Verify that your storage controller and firmware support this drive model before deployment.

  • 1 TB capacity stores large datasets
  • 7200 RPM spindle delivers fast sequential access

Questions about this item

How do I confirm the ST91000640SS is running at 7200 RPM after installation?

Check the drive properties in your RAID controller BIOS or operating system utility; it should report 7200 RPM and a 64 MB cache for this SAS model.

What is included with the ST91000640SS and what must I source separately?

The drive itself is supplied; you will need a compatible 2.5" SAS backplane or cable, a SAS controller or RAID card, and mounting screws for your chassis.

Which capacity version of the Dell Constellation line should I choose for a 1 TB requirement?

The ST91000640SS is the 1 TB variant in this series; select this MPN when you need exactly 1 TB of 7200 RPM SAS storage.
