About the WD Red Pro 12TB NAS Hard Drive
SATA 6Gb/s interface, 3.5-inch form factor, and an MTBF rating of 1,000,000 hours make the WD Red Pro 12TB NAS Hard Drive an exceptionally reliable storage solution for demanding enterprise environments. Manufactured by Western Digital under part number WD121KFBX, this drive delivers the sustained performance and durability that storage architects and IT procurement teams require when building fault-tolerant network-attached storage systems.
The WD Red Pro 12TB combines 12TB capacity with CMR recording technology and a 256MB cache to support continuous 24/7 operation in NAS environments with up to 24-bay configurations. Running at 7200 RPM, the drive handles an annualized workload rating of 300TB per year, while NASware 3.0 firmware ensures seamless integration and optimized performance across heterogeneous storage arrays. Power efficiency is built in—drawing just 7.4W during read/write operations and 1.1W in standby mode—making this Western Digital solution cost-effective for large-scale deployments. Operating across a temperature range of 0°C to 65°C and weighing 730g (typical), the drive's compact 3.5-inch footprint (147.0 x 101.6 x 26.1 mm) fits standard rack and chassis mounting requirements without compromise.
