Enterprise 4 TB hard drive for servers

This Toshiba MG04ACA400N is a 3.5" internal hard drive built for server and workstation environments that require 512 native sector formatting. It delivers 4 TB of storage on a SATA/600 interface with a 7200 rpm spindle speed and 128 MB buffer.

4 TB capacity with 128 MB buffer for sustained

The drive handles continuous read and write streams typical of bulk storage, backup targets and near-line archives. Performance tapers off under heavy random I/O or when the 128 MB cache is saturated by concurrent high-queue-depth requests.

Robust 3.5" build with standard SATA connectors

The 1" high, 4" wide, 5.8" deep chassis weighs 1.59 lb and fits standard drive bays using common SATA data and power cables. Sanitize Instant Erase options are available on some models for rapid data destruction before redeployment.

Questions about this item

Will the 3.5" 4 TB SATA/600 drive fit in the same bay and caddy as my older 3.5" SATA drives?

Yes. It uses the standard 3.5-inch form factor and SATA interface, so it mounts in any 3.5" bay and connects to the same SATA data and power cables you already use.

How can I verify the drive is running at its rated 7200 rpm and 128 MB buffer after installation?

Check the model string and rotation speed in your BIOS or a tool such as CrystalDiskInfo; both will report 7200 rpm and a 128 MB cache for the MG04ACA400N.

Does the box include mounting screws or a SATA data cable, or must I buy them separately?

The drive ships as a bare OEM unit; mounting screws and a SATA data cable are not included and must be sourced separately.
