Dell 1 TB SAS Laptop Hard Drive

The Dell ST91000640SS is a 2.5 inch internal hard drive with a 1 TB capacity and a 7200 RPM spindle speed. It connects through a 6 Gb/s SAS interface and includes a 64 MB cache. The drive ships in a hot-swap tray.

Suits SAS-equipped laptops and servers

This drive fits systems that support 2.5 inch SAS drives with a 6 Gb/s link. Buyers whose hardware lacks a SAS controller or hot-swap bay cannot install it. Laptops limited to a different physical or electrical interface will need another solution.

6 Gb/s SAS interface decides compatibility

The single specification that determines whether this is the correct part is the 6 Gb/s SAS interface. Verify that the host system provides a matching SAS backplane or controller before purchase.

Questions about this item

How much power does the ST91000640SS draw when running continuously in a server?

The 2.5 inch SAS drive spins at 7200 rpm with a 64 MB cache and a 6 Gb/s interface, so sustained operation will generate typical enterprise 2.5 inch heat and power levels.

Which controller or backplane must I already have to connect this 6 Gb/s SAS drive?

A SAS host bus adapter or RAID controller with a 6 Gb/s SAS port and a 2.5 inch drive bay or hot-swap tray is required for the ST91000640SS.

Will this 7.2k RPM SAS drive work in an older 3 Gb/s SAS backplane without speed loss?

The drive negotiates down to 3 Gb/s on legacy SAS backplanes, so it will function but at the slower link rate of the older hardware.
