5.0 out of 5 stars An updated version of the model 28 April 2012
By Claptonian TOP 50 REVIEWER VINE™ VOICE
There are a few different versions of this drive with slightly different geometries (a few more or a few less sectors) and different buffer memory.

This is the OEM version which is usually supplied in an anti-static sleeve and sold in bulk to computer builders. As such, it will not have the normal retail packaging, fixing screws or the information leaflet. You can buy the screws in packs of about 100 quite cheaply or you may be able to beg a few from anyone who builds or repairs computers. Functionally, there is no other difference between OEM and retail versions. The OEM version tends to be slightly less expensive.

As it does not have the normal protection that the retail pack would normally provide and it has been known for some sellers to do rather stupid things when despatching OEM drives. If you should be a victim to one of these sellers, and purchased via Amazon, I would suggest that you return the drive for refund, purchase from a supplier with more understanding of the product and complain to Amazon!

The distinguishing feature of the Caviar Green series is that the motor speed is not constant. In normal use when writing or reading, it will operate at it maximum rotational speed but when inactive, the motor will slow. This will save a proportion of it its normal wattage. It does mean that the drive needs a moment to reach maximum speed from a lower one.

The drive I received is WD20EARX-00AZ6B0 manufactured in Sep 2011.

It is officially the replacement for the WD Green WD20EARS. Having owned several WD20EARS, I expected this drive to be similar or perhaps better. However the drive I received is massively 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 in late 2010. Why they would put these old components in a brand new drive with faster interface is baffling.

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.

*UPDATE 3/12/2012*

This drive has since died. It lasted a little over 1 year.

The warranty replacement service in the UK is very slow. It took over 3 weeks to receive a new hard-drive. The drive I received was a newer 3-platter version WD20EARX-00PASB0

5.0 out of 5 stars Excellent PVR HDD 19 Mar 2012
Amazon Verified Purchase
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.
