Toshiba MG Series 20TB Enterprise Hard Drive (MG10ACA20TE) – SATA 6Gb/s, 7200 RPM, 512MB Cache, CMR with FC-MAMR

The Toshiba MG Series 20TB (MG10ACA20TE) is a 3.5-inch CMR hard drive for enterprise servers, cloud and data center storage. With 7200 RPM operation, a 512MB cache and SATA 6Gb/s connectivity, it gives IT teams and integrators dependable capacity for always-on workloads.

20TB of CMR storage tuned for enterprise workloads.

Why Enterprise Workloads Need the Right Drive

Enterprise servers and cloud storage run constant I/O in dense chassis, where consumer drives fail early and slow rebuilds threaten service levels.

The Toshiba MG Series 20TB is engineered for this role with CMR recording, rotational vibration sensors and firmware tuned for enterprise duty (workload rating: 550TB per year). At 20TB per drive, it cuts the number of bays needed for the same usable capacity, which lowers power draw and simplifies enterprise expansion.

Performance Where It Counts

A 7200 RPM spindle and 512MB cache deliver sustained throughput for server and array workloads. The SATA 6Gb/s interface is backward compatible with SATA 3Gb/s ports and works with standard SATA controllers, NAS bays and server backplanes.

Reliability for Continuous Operation

Toshiba’s rotational vibration sensors and firmware tuning keep the drive stable in multi-bay enclosures running around the clock.

Setup Instructions

How to Install the Toshiba MG Series 20TB
