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.

Questions about this item

How much power does the 55RMX draw during continuous 7200 RPM operation?

The 2.5" SAS 6Gb/s drive runs at 7200 RPM with a 500GB capacity, a profile typical for server workloads in PowerEdge 2970, R900 and R905 systems.

What connector or controller does my chassis need to accept this 2.5" SAS 6Gb/s drive?

A SAS 6Gb/s backplane or HBA with a standard 2.5" drive bay is required; the bare drive slides directly into PowerEdge M605, M805 or PowerVault MD1120 sleds.

Will the 55RMX work in a PowerEdge 2970 that currently uses 3.5" SAS drives?

No — the 2.5" form factor only fits 2.5" bays; the 2970 supports this model in its 2.5" configurations alongside M605, M805, M905, R900 and R905 servers.
