Toshiba MG10 20 TB SATA Hard Drives

Rethink Your Data Storage
Toshiba Enterprise HDDs

The MG10 Series features Toshiba’s fourth-generation, 10-disk Helium-sealed design to advance Conventional Magnetic Recording (CMR) density to 2TB per disk, achieving a total capacity up to 20TB. The industry-standard 3.5-inch form-factor provides 7200rpm performance, and integrates easily into cloud-scale storage infrastructure, business-critical servers and storage, and File and Object storage solutions.

The massive 20TB CMR capacity is delivered using Toshiba’s innovative Flux Control Microwave Assisted Magnetic Recording (FC-MAMR™) technology. These advances help the MG10 Series to achieve optimum storage capacity and application compatibility, with unsurpassed data reliability. Available with a SATA 6.0Gbit/s interface, the MG10 Series models integrate easily into standard 3.5-inch drive bays to help reduce the footprint and operational burden of cloud-scale storage infrastructure, File and Object storage systems, and business critical servers and storage systems.
