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

This is the second drive I have bought as the first one works very good, data transfer is fast and since I use a H D D docking station so that it essentially act like an external hard drive.So saying that I would recommend it as an internal drive as well.

Purchased over 8 months ago and still performing well. Relatively silent and handles all the work i throw at it. Not using as a boot drive but as storage it works a treat.

I have just reviewed a USB 3.0 docking station with USB card reader and my review is in relation of this HDD with that utility. I have had for a couple of years now, an eSATA docking station so that I could use drives without the need for opening the PC case. It was OK but firmware issues meant I had to reboot the PC if I wanted to change the disk, hot swapping wouldn't work.

With the USB 3.0 one, this has changed and opened up horizons for out-of-caddy drives. Enough of the prequel. I already have one of these drives (WD20EAX, so very slightly different). This I use for backup of my home-studio which generates something up to 100GB of data per song (96kHz) where a single instrument in one track easily surpasses 200-300 MB. This data is precious and irreplaceable as you can imagine, so reliability is the word. The studio has the performance scratch disks so what I needed was efficient, dependability. These drives deliver that in abundance. Low power and on the USB 3.0 docker, backups churn away quietly at a respectable 100 MBpS which means I'm not waiting around forever. I have a couple now so take one off-site to ensure that if there is a fire or some other disaster, I have backups to a few days ago secure in another location.

I wouldn't use one of these for a scratch disk for video or audio work but they have a huge thumbs up for storage & retrieval. 10/10 WD.

I bought 2 of these drives from Amazon in June 2012 and BOTH had failed by September! I have bought dozens of drives in my time and I have had drives fail before, but not this quickly and not 2 at a time. Looking online I find that I'm not the only one that this has happened to. They were being used purely as storage, my OS is on an SSD. Look elsewhere for your internal HDDs, you have been warned.

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.

Update 2: 21 August 14. Still chugging along perfectly!
