Dell 4TB 3.5" SAS 12Gb/s Hard Drive

The Dell 400-ALRV is a new 4TB nearline SAS hard drive in a 3.5 inch form factor. It spins at 7200 RPM and connects through a 12Gb/s SAS interface. The drive is supplied as a bare unit with a hot-swap tray for tool-less installation in compatible bays. It is built for desktop and server storage arrays that use SAS controllers.

Ideal for SAS storage arrays and hot-swap bays

This drive suits administrators expanding SAS-based RAID or JBOD arrays that require 12Gb/s throughput and hot-swap capability. It is not for systems that lack a SAS host bus adapter or backplane. Buyers needing a different capacity or a non-hot-swap mounting method should look at other models.

12Gb/s SAS interface and hot-swap tray

The single specification that decides fit is the 12Gb/s SAS interface combined with the hot-swap tray type. The controller and chassis must support SAS 12Gb/s signalling and accept the supplied tray format for the drive to function.
