Dell 400-ATJR 1.8TB SAS 12Gb/s drive

This 1.8TB internal hard drive uses a SAS 12Gb/s interface and spins at 10000 RPM. It fits a 2.5-inch hot-swap bay and is supplied new. The 512e format provides high capacity for demanding storage arrays.

Suits servers needing fast 10K SAS storage

This drive suits administrators who need 10000 RPM performance over a 12Gb/s SAS link in a 2.5-inch form factor. It is not for systems that lack a SAS controller or backplane. Buyers who require 512n native sector support should look elsewhere. VMware environments cannot use this 512e drive.

Critical spec: SAS 12Gb/s interface

The drive communicates exclusively through a SAS 12Gb/s connection. A compatible SAS host bus adapter or RAID controller is mandatory for operation. The 512e sector format requires Windows Server 2008 R2 or later, UEFI boot on Windows Server 2012, or supported Linux distributions.

Questions about this item

Will this 1.8TB 10K SAS 12Gb/s drive work in a server that currently uses 2.5-inch 6Gb/s SAS drives?

The drive uses the SAS 12Gb/s interface, which is backward compatible with 6Gb/s SAS backplanes. It fits the same 2.5-inch hot-swap bays, so it can be added alongside existing 6Gb/s drives without hardware changes.

How can I verify the 10,000 RPM spindle speed and 12Gb/s link are active after installation?

Check the controller BIOS or management utility; it should report the negotiated link speed as 12Gb/s and the drive model 400-ATJR with a 10,000 RPM spindle. SMART data will also confirm the rotational speed.

Does the 400-ATJR ship with a drive tray or caddy, or must I supply my own?

The drive is supplied as a bare 2.5-inch hot-plug unit. Dell servers require a generation-specific drive tray or caddy, which is not included and must be purchased separately if your chassis does not already have one.
