About the Toshiba MG11 20TB 3.5″ Enterprise Hard Drive
The Toshiba MG11 20TB is an enterprise-class 3.5-inch SATA hard drive for servers, storage arrays and NAS systems that run around the clock. It uses a helium-sealed design with conventional magnetic recording and Toshiba’s FC-MAMR technology, spins at 7200 RPM and has a 1 GiB buffer. Toshiba rates the drive for 550TB of data per year with an MTTF of 2.5 million hours. The 512e format suits current operating systems and controllers, and the 20TB capacity balances cost per terabyte with rebuild times for RAID arrays.
