Server storage drive

The Dell 4X1DR is a 900GB 2.5-inch internal hard drive with a SAS 6Gb/s interface spinning at 10000 RPM. It includes a 32MB buffer and ships in an R-Series tray designed for Dell PowerEdge servers and PowerVault MD1220 storage systems.

Suited for compatible servers

This drive fits Dell PowerEdge C, M, R and T series servers listed in the compatibility data, including models such as the R620, R720, R820 and T620. It is not for systems that do not accept a 2.5-inch SAS drive with an R-Series tray.

SAS 6Gb/s interface

The single specification that decides fit is the SAS 6Gb/s interface combined with the R-Series tray; the host must support this exact connection and mechanical format for the drive to function.

Questions about this item

What throughput does the 6Gb/s SAS interface deliver in practice?

The 6Gb/s SAS link provides up to 6 gigabits per second of raw bandwidth; actual throughput depends on the host controller and workload.

What physical space and tray does this 2.5" drive require?

It fits a standard 2.5-inch bay and ships with an R-Series tray for Dell PowerEdge servers.

How is the drive installed, and which step is often missed?

Slide the drive into the R-Series tray, secure the screws, then insert the tray into the hot-swap bay until the latch clicks; the step often missed is fully seating the latch to engage the SAS connector.
