Dell 400-AFTY 1.2 TB SAS Drive

The Dell 400-AFTY is a 1.2 TB 2.5 inch SAS hard drive spinning at 10000 RPM with a 12 Gb/s interface. It is built for servers and storage arrays that require a hot-swap 2.5 inch form factor. The bare drive carries Dell part number 400-AFTY and is supplied new.

Who This Suits And Who It Does Not

This drive suits administrators expanding Dell PowerEdge or compatible SAS backplanes that accept 12 Gb/s 10 K RPM drives. It is not for systems that lack a SAS controller or hot-swap bays. It is not for workloads needing solid-state latency or higher capacity per bay.

Deciding Specification

The 12 Gb/s SAS interface is the single specification that decides compatibility; the host backplane and controller must support 12 Gb/s SAS signalling for the drive to operate.

Questions about this item

How much power and heat does the 10000 RPM 2.5" drive produce during all-day operation?

The 10000 RPM spindle and 12Gb/s SAS interface draw more power and generate more heat than slower drives; ensure your chassis has adequate airflow for 2.5" bays.

What controller or backplane must my system provide for the 12Gb/s SAS interface to work?

A SAS HBA, RAID controller or hot-swap backplane with 12Gb/s SAS ports is required; the drive uses a standard SAS connector and supports hot-swap trays.

Will the 1.2TB 12Gb/s SAS drive work in a Dell PowerEdge server that currently uses 6Gb/s SAS drives?

Yes, the 12Gb/s SAS drive is backward compatible with 6Gb/s SAS backplanes and controllers; it will negotiate the lower link speed automatically.
