Purpose-built enterprise storage

The Dell 400-ATJM is a 1.2TB 2.5-inch internal hard drive spinning at 10000 RPM. It uses a SAS 12Gb/s interface for high-throughput data transfer. The drive is sold new and targets servers or workstations that require fast, reliable primary storage.

Suits high-IO workloads, not archival

This drive suits database servers, virtualisation hosts and transaction-heavy applications that benefit from low latency and sustained throughput. Buyers needing maximum capacity per bay or silent operation for desktop media libraries should consider alternatives better matched to those priorities.

SAS 12Gb/s interface determines compatibility

The single specification that decides fitment is the SAS 12Gb/s interface; the system must provide a compatible SAS backplane or controller. Without that connection the drive cannot communicate, regardless of its 10000 RPM speed or 1.2TB capacity.

Questions about this item

How loud and hot does the 10000 RPM drive get when running all day?

The 10000 RPM spindle speed and SAS 12Gb/s interface are designed for continuous enterprise workloads; typical 2.5" drives at this speed run within standard server thermal and acoustic limits.

What controller or backplane must I already have for the SAS 12Gb/s interface to work?

You need a host bus adapter, RAID controller or server backplane that supports 12Gb/s SAS signalling and a 2.5" drive bay.

Will the 2.5" 10000 RPM drive fit and function in my older server that only takes 3.5" bays?

The drive is a 2.5" form factor, so it requires a 2.5" bay or a 3.5" adapter tray; it will not mount directly in a native 3.5" slot.
