The WD4000KS-00MNB0 is a Western Digital Caviar SE 400GB 3.5-inch hard drive designed for enterprise and high-performance computing environments. It features a 7200 RPM spindle speed with a 16MB cache buffer and SATA 3 Gb/s interface, delivering sustained throughput suitable for server and storage array applications. The SE-16 line targets systems requiring reliability in 24/7 operation, including RAID arrays, network-attached storage (NAS), and backup infrastructure where consistent data access patterns are expected.
This drive is compatible with standard 3.5-inch hot-swap bays and legacy server chassis from the early-to-mid 2000s era. Typical deployment includes lower-tier storage in mixed-capacity arrays, archival systems, or cost-sensitive backup applications where 400GB capacity serves as a secondary or tertiary tier. The SATA interface integrates with standard server motherboards and HBA controllers without requiring specialized drivers.
All units are tested and guaranteed for immediate deployment. Available via quote.
