4 TB SAS drive for servers

This 3.5-inch internal hard drive provides 4 TB of storage on a SAS 12Gb/s interface and spins at 7200 RPM. It is supplied as a replacement kit and intended for Dell PowerEdge 14th and 15th generation rack and tower servers.

Sustained 7200 RPM operation

The spindle maintains 7200 RPM continuously, so sequential throughput stays steady during long write or rebuild jobs rather than dropping after a short burst. The SAS 12Gb/s link keeps the bus saturated under heavy multi-threaded workloads typical of database or virtualisation hosts.

Check SAS backplane and tray fit

Verify that your chassis accepts 3.5-inch SAS drives and that the backplane supports 12Gb/s signalling. Confirm the server model appears in the supported PowerEdge 14th or 15th generation list and that a compatible drive carrier is available.

Questions about this item

How much power does the 7200 RPM SAS 12Gb/s drive draw during continuous operation?

The 3.5" 4TB drive is rated for typical enterprise workloads in Dell PowerEdge 14G and 15G servers, with power consumption optimised for 24/7 use in those platforms.

What controller or backplane is required to run this SAS 12Gb/s drive?

A SAS 12Gb/s host bus adapter or a server backplane that supports 12Gb/s SAS is needed; the drive uses a standard SAS interface and fits 3.5" hot-plug bays in the listed Dell PowerEdge models.

Will this 4TB 7200 RPM SAS drive work in the Dell PowerEdge R740xd and R750xs servers I already have?

Yes, the drive is validated for Dell PowerEdge 14G servers such as the R740xd and 15G servers such as the R750xs, so it will install and operate in both generations.
