Western Digital's 4 TB WD4001FAEX Review: Back In Black

Western Digital has a new 4 TB flagship. Its WD4001FAEX is part of the companyís Black family of performance-oriented drives. Spinning at 7,200 RPM, it might seem at home in a high-end desktop, but our numbers suggest it might fare better in a server.

Western Digital recently added a new model to its Black family of performance-oriented hard drives. The new disk, technically referred to as WD4001FAEX, sports 4 TB of space. It spins at 7,200 RPM, employs a 6 Gb/s SATA interface, and includes 64 MB of cache.
