Dell Cheetah 15K.5 73 GB SAS Drive

This 3.5-inch internal hard drive delivers 73 GB of storage on a 15 000 RPM spindle with a 3 Gb/s SAS interface and 16 MB cache. It ships new with zero power-on hours and includes a Dell R-series caddy for direct installation in compatible bays.

Suited for legacy SAS arrays and 3.5-inch bays

The drive fits servers or workstations that accept 3.5-inch SAS disks and benefit from 15 000 RPM rotational speed for transactional workloads. Buyers who need larger capacities, solid-state latency or a different physical interface should look at something else.

3 Gb/s SAS interface and 15 000 RPM spindle

The single specification that decides fit is the 3 Gb/s SAS connection combined with 15 000 RPM rotation; the host backplane and controller must support this exact interface and speed for the drive to function.
