Epoch 84KR4 4TB SAS 12Gb/s server drive

This 3.5-inch internal hard drive delivers 4TB of storage over a SAS 12Gb/s interface at 7200 RPM. It is supplied as a replacement kit validated for Dell PowerEdge 14 and 15 Generation rack and tower servers. The drive is new and built with genuine components for enterprise environments.

Suited for Dell PowerEdge 14G

This drive fits the listed R240 through R940xa and T150 through T550 models that require a 3.5-inch SAS 12Gb/s disk. It is not for systems limited to 2.5-inch bays or those requiring a different interface protocol. Buyers needing higher capacity or a different form factor should consider other options.

SAS 12Gb/s interface confirms server compatibility

The single specification that decides fitment is the SAS 12Gb/s interface combined with the 3.5-inch form factor. Only servers equipped with matching SAS backplanes and 3.5-inch drive carriers can use this kit. Verify your chassis and controller support this exact interface before purchase.

Questions about this item

Does my server need a SAS 12Gb/s backplane to use this 4TB 7200 RPM drive?

Yes, the drive connects through a SAS 12Gb/s interface and requires a compatible backplane or controller that supports that speed.

Will this 3.5" SAS drive work in my older Dell PowerEdge 14G server alongside existing drives?

It is listed as compatible with Dell PowerEdge 14G models such as the R640, R740, R740xd and R940, so it can operate alongside other drives in those chassis.

How can I confirm the drive is recognised at 12Gb/s after installation?

Check the server BIOS or RAID controller utility; it should report the drive running at the full SAS 12Gb/s link speed with 4TB capacity.
