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.

Terrible service from WD.

Much like the other review, I found out the hard way that you have to ship the hard drive back to Vietnam...which costs ~$40AUD and will likely take 1-2 months before I get a replacement. The fact that the drive is only ~6months old is also not a good sign.

Think twice before ordering WD disks. They took over 5 weeks to replace my broken drive under warranty, and all this time I did not have the drive available. Contributing factors were: * Shoppingexpress does not respond to emails about warranty; you have to call them and they will refer you to WD * WD has a worldwide offer where they first provide a new drive and afterwards you send in the broken one, EXCEPT FOR AUSTRALIA. Yes that's correct, Australians are the only ones who will first have to ship their faulty drive before getting a replacement * You will have to ship to VIETNAM, which takes about a week and a half each way * WD will take about a week to assess whether you original drive is really broken -------------- So, unless you don't really need the drive, I wouldn't buy WD
