Western Digital announced today the new 3.5-inch SATA hard drive that's specifically designed for home and small office NAS systems of up to five drive bays. WD says the WD Red has been tested with "top NAS box manufacturers" and is optimized for power and performance.
According to WD, 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.
The new drive 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. WD says 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.
The WD Red hard drive is available now in 1TB (model number WD10EFRX), 2TB (WD20EFRX), and 3TB (WD30EFRX) capacities that are slated to cost $109, $139, and $189, respectively. Soon you will also find them pre-installed inside NAS servers.
