Enterprise and data centre drives are built for constant duty, higher workload ratings and longer warranties than consumer models, which is why they fill servers, large NAS arrays and nearline storage. This page ranks the enterprise class drives we track on Amazon.co.uk by price per terabyte, covering Seagate Exos, WD Ultrastar and Red Pro, Toshiba MG and SAS units. UK prices refresh through the day. Even at the high end, price per terabyte is the fair way to compare, and the biggest nearline drives often lead it. Filter by capacity or brand to size a build before you buy.
