About the Toshiba MG11 22TB 3.5″ Enterprise Hard Drive
The Toshiba MG11 22TB is a SATA enterprise hard drive for data centre, server and large NAS deployments that need dense storage in a standard 3.5-inch bay. Its helium-sealed mechanism spins at 7200 RPM, uses CMR with FC-MAMR, and has a 1 GiB buffer to handle mixed workloads. Toshiba rates it for 550TB per year and 2.5 million hours MTTF, with typical idle noise of 20 dB. The 22TB capacity raises storage per bay for growing arrays while keeping a simple SATA interface and 512e sector format.
