Enterprise capacity drive

The Toshiba MG10ACA20TE is a 20TB 3.5-inch internal hard drive built for enterprise storage workloads. It runs at 7200 RPM with a 512MB cache on a SATA 6.0Gb/s interface. A 10-disc helium-sealed design supports the high capacity and 24x7 reliability rating.

Who this suits and who it does not

This drive suits arrays, servers and NAS units that need maximum sustained capacity on a standard SATA connection. It is not for systems that require a 2.5-inch form factor or a smaller capacity point. Buyers needing portable external storage or laptop upgrades should look elsewhere.

The deciding specification

The 20TB capacity is the single figure that determines fit. It dictates whether the drive meets the raw storage target for the intended volume or RAID set. Confirm the host supports 20TB SATA drives and 512e advanced formatting before purchase.

Questions about this item

Does the MG10ACA20TE ship with a SATA cable and mounting screws, or do I need to source them separately?

The drive is supplied in retail or OEM packing that may vary; cables and screws are not guaranteed, so plan to provide your own SATA data cable, power connector and 3.5" mounting hardware.

The spec sheet lists a single 20TB capacity — are there other capacities in the MG10ACA line that I should consider instead?

This MPN is the 20TB model; other MG10ACA capacities carry different part numbers, so choose the 20TB unit when you need that exact raw space.

With 7200 RPM and a 512MB cache, what kind of sustained throughput can I expect once the drive is installed in a desktop?

The 7200 RPM spindle and 512MB buffer deliver enterprise-class sustained transfer rates suitable for 24x7 workloads such as NAS, surveillance or bulk storage arrays.
