12 TB SAS 12 Gb/s 3.5" drive

This Epoch 400-BEKN kit supplies a 12 TB enterprise hard drive that spins at 7200 RPM and connects through a SAS 12 Gb/s interface. The 3.5 inch form factor fits standard server drive bays. It is intended for administrators who need high-capacity storage in compatible Dell PowerEdge systems.

Suits Dell PowerEdge Gen 14 and 15 servers

The drive is validated for Dell PowerEdge 14th and 15th generation rack servers including R240 R340 R440 R540 R640 R6415 R740 R740xd R740xd2 R7415 R7425 R840 R940 R940xa as well as 15th generation models R250 R350 R450 R550 R550P R650 R650xs R6515 R6525 R750 R750xa R750xs R7515 R7525 and tower models T150 T350 T550. It does not suit builders who need a different interface or a smaller form factor.

SAS 12 Gb/s interface decides fit

The single specification that determines compatibility is the SAS 12 Gb/s interface. Only systems with a matching SAS backplane or controller can use this drive. Verify the server specification before purchase.

Questions about this item

Does my server need a 12Gb/s SAS controller to run this 12TB drive?

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

Will this 3.5" 7200 RPM drive fit in a Dell PowerEdge R740xd that currently uses 10K SAS drives?

It fits any 3.5" bay in the listed 14G and 15G PowerEdge servers, but the 7200 RPM speed is slower than 10K drives you may keep alongside it.

How can I confirm the 12TB capacity is recognised after installation?

Check the RAID controller BIOS or the operating system disk utility — both should show the full 12TB capacity and a healthy SMART status.
