About the Toshiba MG09 14TB 3.5″ Enterprise Hard Drive
The Toshiba MG09 14TB is a 3.5-inch SATA enterprise hard drive for servers, NAS arrays and backup systems that run continuously. It uses a helium-sealed design with conventional magnetic recording, spins at 7200 RPM and pairs a 512 MiB buffer with a sustained transfer rate of about 281 MB/s. Toshiba rates it for a 550TB per year workload and 2.5 million hours MTTF, with idle power of 3.77 W. The 14TB capacity is a practical size for small business storage and RAID arrays where rebuild time and cost per terabyte both matter, and it comes with Toshiba’s five year limited warranty.
