DELL 55RMX 500GB 7200 RPM SAS 6Gb/s 2.5" internal hard drive

Server-Grade SAS Drive

The Dell 55RMX is a 500GB 2.5-inch internal hard drive spinning at 7200 RPM with a SAS 6Gb/s interface. It is supplied as a bare drive in new condition and is listed as compatible with specific PowerVault and PowerEdge server models including the MD1120, 2970, R900, R905 and M-series units. This makes it a direct-fit component for maintaining or expanding those storage arrays.

Suited for Supported Dell Arrays

This drive suits administrators replacing a failed unit or adding capacity to the exact Dell systems named in the compatibility list. It is not suited for servers or controllers that lack a SAS 6Gb/s backplane, for any system outside the listed Dell PowerEdge and PowerVault models, or for workloads demanding higher capacities or solid-state performance. The bare-drive packaging also means no mounting tray is included for hot-swap bays.

SAS 6Gb/s Interface Decides Fit

The single specification that determines whether this is the right part is the SAS 6Gb/s interface combined with the 2.5-inch form factor. Only systems equipped with a compatible SAS backplane and the physical bay space for a 2.5-inch drive can accept it. Verify the host controller and chassis support SAS signalling at 6Gb/s before ordering.
