  • 1 TB capacity for large datasets

  • Includes PowerEdge server tray for direct installation

Server storage upgrade

The Dell Constellation.2 ST91000640SS is a 1000GB SAS hard drive spinning at 7200RPM with a 64MB cache. It arrives new in a 2.5 inch form factor and includes a compatible caddy tray for direct installation. The drive is designed for PowerEdge servers such as the R610, R710, T410 and M610.

Fit for PowerEdge bays

This drive suits administrators replacing a failed disk or adding capacity to the listed PowerEdge models where a 2.5 inch SAS bay is available. It is not for systems that lack a SAS backplane or cannot accept the supplied tray. Buyers needing a different interface or a 3.5 inch form factor should look elsewhere.

Interface decides compatibility

The single specification that determines fit is the 2.5 inch SAS 6Gb/s interface. Only servers with a matching SAS backplane and the correct tray dimensions can use this drive.

  • 7200 RPM spindle for fast data access

Questions about this item

Does the drive ship with the server tray included or must it be purchased separately?

The listing includes the Dell PowerEdge caddy/tray so the drive can be installed directly in a compatible bay.

Which capacity and speed variant matches the ST91000640SS model?

This is the 1000GB model spinning at 7200RPM with a 64MB buffer and SAS 6Gb/s interface.

What sustained throughput can be expected from the 6Gb/s SAS link inside a PowerEdge server?

The 6Gb/s SAS interface supports up to 600MB/s theoretical bandwidth; real-world throughput depends on the controller and workload.
