Dell 1 TB 7200 RPM SAS drive

This Dell branded drive uses the Seagate Constellation2 platform in a 2.5 inch small form factor. It delivers 1 TB of storage at 7200 RPM and connects through a 6 Gb SAS interface. The unit is supplied new in OEM packaging.

Enterprise arrays and compatible servers

The drive fits servers and storage arrays that accept 2.5 inch SAS devices and can address 7.2K spindle speeds. It will not work in systems that only provide SATA ports, nor in laptops with strict z-height limits. Buyers needing SSD response times or larger capacities should consider other options.

6 Gb SAS interface

The single specification that determines fit is the 6 Gb SAS connection; the host must present a matching SAS backplane or controller. Without that interface the drive cannot be used, regardless of its physical size or capacity.

Questions about this item

Does the DELL ST91000640SS 1TB 7.2K SAS 2.5" drive ship with a mounting bracket or caddy, or must I source one separately?

The supplier notes that retail or OEM packing may vary, so the drive may arrive without a mounting bracket or caddy; check your chassis or server manual for the correct 2.5" SAS carrier.

Should I choose the 7.2K 6G SAS version or a different speed and interface for a Dell PowerEdge server?

This model is a 7200RPM 6Gb/s SAS drive in a 2.5" form factor; select it when your server backplane supports 6G SAS and you need 1TB of 7.2K nearline storage.

What does the 7.2K 6G SAS rating mean for actual throughput in a RAID array?

The 7200RPM spindle and 6Gb/s SAS link deliver sustained transfer rates typical of nearline SAS drives; real-world throughput depends on RAID level, controller cache and workload mix.
