This Toshiba Enterprise Capacity MG Series drive (retail kit HDEPZ13GEA51F) offers 12TB in a standard 3.5-inch form factor for servers, storage arrays and high-capacity NAS systems that run around the clock. It spins at 7,200RPM over a SATA 6Gb/s interface, with a 256MB cache and 512e (Advanced Format) sector emulation, and is rated for continuous 24/7 operation with a 2.5-million-hour MTBF according to reseller specifications. Enterprise MG drives are built for heavier duty than desktop or entry NAS drives, which makes this a solid option for file servers, backup and archive targets, virtualisation hosts and video surveillance storage in South African businesses that need dependable bulk capacity. The drive fits standard 3.5-inch server and NAS bays and backplanes. It ships as a single drive in Toshiba retail packaging; confirm the local warranty period with the supplier when ordering.
