WD Expansion Kit WDBNSW0040HNC - hard drive - 4 TB - SATA 6Gb/s

Upgrade the storage capacity on your WD Sentinel small office storage server. As demand for storage continues to expand, the need for more efficient power solutions becomes paramount. WD T3 enterprise SATA hard drives make it possible for large-scale data centers to increase storage capacity without exceeding available power, and in many cases actually reducing power consumption. WD T3 drives help combat the four major challenges large data installations face - total drive slots, maximum capacity, power allotment, and financial constraints - while lowering the total cost of ownership.
