About the Toshiba N300 12TB 3.5″ NAS Hard Drive
The Toshiba N300 12TB is a 3.5-inch SATA hard drive built for always-on NAS units in homes and small businesses. It spins at 7200 RPM with a 512MB buffer and uses conventional magnetic recording (CMR) in a helium-sealed design, which suits RAID arrays and frequent rebuilds. The drive is rated for 24/7 operation, a workload of 180TB per year and an MTTF of 1.2 million hours. Rotational vibration and shock sensors help it stay stable when several drives sit side by side. This retail-packaged version carries Toshiba’s 3 year warranty.
