DELL ST3450857SS 450GB 15000RPM 3.5" SAS internal hard drive

450 GB 15 000 RPM SAS drive

The Dell Cheetah 15K.7 is a 450 GB 3.5-inch internal hard drive spinning at 15 000 RPM with a 6 Gb/s SAS interface and 16 MB cache. It ships new with an R-series caddy for direct mounting in compatible bays.

Suited for high-IOPS server workloads

This drive targets administrators who need low-latency random access in SAS-equipped arrays or servers. Buyers who need larger capacity per spindle, lower power draw, or a different physical interface should consider other options.

6 Gb/s SAS interface is the fit criterion

The drive connects exclusively via 6 Gb/s SAS; the host backplane or controller must provide a matching SAS port and support 3.5-inch form factor. Without that interface the drive cannot be installed.
