Dell Constellation.2 500GB SAS Drive

This new 2.5-inch internal hard drive delivers 500GB capacity at 7200RPM with a 6Gb/s SAS interface and 64MB cache. It ships with a Dell PowerEdge caddy for direct installation in supported server bays. The Constellation.2 55RMX model is built for enterprise workloads requiring consistent rotational speed.

Suits administrators expanding compatible

IT teams maintaining the listed PowerEdge models from the M600 through T710 series can add matched storage without adapter brackets. Buyers who need a different interface protocol, higher areal density, or drives qualified for non-Dell chassis should evaluate other options.

6Gb/s SAS interface determines controller

The drive communicates over a 6Gb/s SAS link, so the host controller or backplane must support that exact signalling rate. Verify the server's storage controller specifications before purchase to ensure the interface matches.

Questions about this item

How much heat and noise does the 7200RPM SAS drive add when it runs continuously in a server?

The 7200RPM spindle and 64MB cache produce typical enterprise 2.5" SAS heat and acoustic levels; the 1.0 pound weight keeps vibration low in a PowerEdge caddy.

Which controller or backplane must my system already have for the 6Gb/s SAS interface to work?

A SAS 6Gb/s backplane or HBA with a 2.5" drive bay is required; the included PowerEdge caddy fits Dell M610, R620, T420 and other listed servers.

Will the 500GB SAS drive work alongside older 3Gb/s SAS drives in the same PowerEdge array?

Yes, the 6Gb/s interface auto-negotiates down to 3Gb/s, so it can share a backplane with earlier SAS drives in compatible PowerEdge models.
