Technical Details
- Reduced power consumption - WD has reduced power consumption making it possible for energy conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation
- Cool and quiet - drives that benefit from WD GreenPower Technology yield lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives
- IntelliPower technology - a fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance
- NoTouch ramp load technology - the recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit
- Advanced Format (AF) - technology being adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities

The drive I received is WD20EARX-00AZ6B0 manufactured in Sep 2011.
It is officially the replacement for the WD20EARS. However the drive I received is significantly slower than my existing WD20EARS. Average read speed is 84MB/s according to HD Tune, compared to 106MB/s on my WD20EARS. 22MB/s, big difference!
I was also disappointed to note that it has 4x500GB platters. This is old technology, Western Digital introduced 667GB platters over 1 year ago.
You should care about this because with 667GB per platter you only need 3 platters for a 2TB drive, hence they have less components and are more reliable. Also higher density platters generally have better sequential performance (assuming the rotational speed is the same). Finally, less spinning mass = less vibration and less power consumption.
I think it is very cheeky of WD to release a brand new, more expensive replacement for the WD20EARS, make a big deal about the 6Gb/s interface, and then use OLD components and a SLOWER drive. In fact I believe they shipped 3-platter versions of the WD20EARX as review units because I have seen pics of WD20EARX on review sites that do not look like mine.

I bought this to update my Sky HD hard drive. It has been in the Sky box for two weeks now, performing flawlessly.
I would recommend this for any PVR use.
Update - 24 Apr 12. As stated above, still performing flawlessly. The drive is very, very quiet in operation.

Purchased as a media drive for making a PC server. It's been faultless from the off with plenty of speed for such work, although I must admit I don't stream much BluRay quality content. It is a doddle to install and just works. Transfer rates are good with no waiting around for movies.

Very very good but...
Hello, the WD 2T is only little noisy. When I am not listening to music I can hear it and some times it's disturbing. Therefore it is very quick.
