Toshiba MG Series Enterprise 3.5-inch 20TB SATA Internal HDD MG11ACA20TE

Toshiba MG Series Enterprise 3.5-inch 20TB SATA Internal HDD MG11ACA20TE

The Toshiba MG11ACA20TE is a high-capacity 20TB enterprise hard drive developed for data centres, cloud-scale systems, rack-mounted storage, data archives and backup infrastructure. Its helium-sealed 3.5-inch design combines Conventional Magnetic Recording with Toshiba’s second-generation FC-MAMR technology, providing dependable storage density for demanding 24/7 environments.

With a SATA 6 Gbit/s interface, 7,200 rpm rotational speed and a 1 GiB buffer, the drive delivers a typical maximum sustained transfer rate of up to 281 MiB/s. Its 550TB annual workload rating and 2.5-million-hour MTTF make it suitable for storage systems that need to manage large volumes of business-critical data.

High-Capacity Enterprise Storage

The 20TB capacity helps organisations consolidate more data into fewer drive bays, making the MG11ACA20TE a practical option for capacity-optimised servers and storage arrays. Toshiba’s ten-disk, helium-sealed mechanical design reduces aerodynamic drag inside the drive and supports efficient high-density storage.

FC-MAMR and CMR Technology

Second-generation Flux Control Microwave Assisted Magnetic Recording helps increase recording density while retaining Conventional Magnetic Recording behaviour. CMR technology provides predictable write performance and broad compatibility for enterprise workloads, including backup, archival and cloud storage applications.

Designed for Continuous Operation

The MG11 Series is engineered for operation 24 hours a day, seven days a week. A rated annual workload of 550TB, 600,000 load and unload cycles, and a 2.5-million-hour MTTF support use in systems where consistent availability and long-term reliability are important.

Persistent Write Cache Protection

As a 512e model, the MG11ACA20TE incorporates Toshiba Persistent Write Cache technology. This feature is designed to help protect cached data if an unexpected power-loss event occurs.
