The WD Red line features NASware technology that addresses the unique environment of NAS for affordable, reliable, and compatible storage that reduces the total cost of ownership. The WD Red hard drives also feature 3D Active Balance Plus, an enhanced balance control technology designed to improve the overall drive performance and reliability. Supports SATA 3 (6Gbps), comes with 64MB of cache memory, and comes with InteliPower technology that allows it to spin at variable speeds, depending on the demand of the host. The drive offers a sustained real-world speed of about 150MBps, which is more than fast enough for NAS servers, of which the data transfer speed is typically limited by the Gigabit network connection that caps at125MBps.
