HDD Toshiba 20 TB 3.5" Serial ATA MG10ACA20TA

The Toshiba MG10ACA20TA is a 3.5-inch enterprise-class internal hard drive that delivers up to 20 TB of Conventional Magnetic Recording (CMR) capacity. Built on a 10-disk helium-sealed design and operating at 7200 RPM, this Serial ATA drive is intended for cloud-scale storage, business-critical servers, and file and object storage systems. The model uses Toshiba’s FC-MAMR technology to increase areal density while maintaining application compatibility and data reliability.

Advantages

The MG10 Series combines a massive 20 TB CMR capacity with a 3.5-inch, 7200 RPM form factor and SATA 6.0 Gbit/s interface for straightforward integration into standard drive bays. Toshiba’s helium-sealed 10-disk design and Precision Laser Welding reduce aerodynamic drag and lower operational power consumption. Persistent Write Cache Technology on supported models provides protection against data loss in sudden power-loss events, helping to ensure enterprise-grade reliability and lower total cost of ownership (TCO).
