The WD400BB-00DEA0 is a 40GB Western Digital Caviar SE 3.5-inch hard drive featuring a 7200 RPM spindle speed and 2MB cache buffer. It connects via ATA-100 (PATA) interface, supporting throughput up to 100 MB/s, and is compatible with legacy desktop systems and servers from the early-to-mid 2000s era. Typical applications include storage expansion in older workstations, archival systems, or replacement drives for discontinued equipment where modern SATA or SAS drives are incompatible.
This drive is well-suited for non-critical storage needs in environments where PATA infrastructure remains in place. Capacity and performance are suited to general file storage rather than high-demand transactional or streaming workloads.
Tested and guaranteed. Available via quote.
