About the Toshiba MG11 24TB 3.5″ Enterprise Hard Drive
The Toshiba MG11 24TB is the largest drive in Toshiba’s MG11 enterprise range, using a 10-disk helium-sealed design at 2.4TB per disk. It is a 3.5-inch SATA drive that spins at 7200 RPM with a 1 GiB buffer and CMR recording assisted by FC-MAMR. Toshiba rates it for 550TB per year and an MTTF of 2.5 million hours, so it suits servers, backup targets and NAS arrays running 24/7. The 24TB capacity delivers the most storage per bay in this batch, which helps reduce drive count and power per terabyte.
