  • 500 GB capacity stores large datasets
  • 7200 RPM spindle speed delivers fast data access
  • 64 MB cache buffers bursts for smoother throughput
  • SAS 6 Gb/s interface ensures reliable enterprise connectivity
  • 5 inch hot-swap tray allows quick drive replacement

Dell 55RMX 500GB SAS Drive

The Dell 55RMX is a 2.5 inch internal hard drive with a 500GB capacity. It operates at 7200 rpm with a 64MB buffer and connects via a 6Gb/s SAS interface. The unit ships in a hot-swap tray.

Suited for 2.5-inch SAS bays

This drive fits servers and arrays that accept 2.5 inch SAS drives running at 6Gb/s. It is not for systems limited to 3.5 inch drive bays. Buyers needing larger capacities should look at other models.

6Gb/s SAS interface decides fit

The single specification that determines compatibility is the 6Gb/s SAS connection. Your backplane or controller must support this exact interface and speed. The 2.5 inch form factor and 7200 rpm speed are secondary constraints.

Questions about this item

Which capacity version of the Dell 55RMX should I select for a 500 GB requirement?

This model is offered in a single 500 GB capacity, so it matches that requirement directly.

What does the 7.2k RPM spindle speed deliver in a live system?

The 7200 rpm rotation provides faster sequential throughput and lower average latency than slower-spinning drives, improving application load times and file transfers.

How does the SAS 6 Gb/s interface limit real-world performance?

The 6 Gb/s SAS link caps the external transfer rate, so sustained reads and writes cannot exceed that bandwidth regardless of the drive's internal speed.
