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.

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.

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 would have given 5 stars for this if it were not for the fact that the packaging was nothing more than cardboard inside another cardboard box.

To be a little clearer, the HDD was wrapped in one smaller-than-A4 piece of bubble wrap, put in a cardboard box and then placed in another bigger box with a nest of brown paper put around the edge. Not the best for a hard drive to be shipped in.

As a result, I felt it necessary to run diagnostics on the drive to satisfy my concern that something could be wrong.

I'm not going to comment on the speed of the drive, as I am going to use this in a RAID 1 array for backup purposes.

Otherwise, the item itself is as described and shipping was quick.

All I can say is that Western Digital have made a great HD and at such a brilliant price it is unbeatable. It started to work the moment I installed it in my NETGEAR ReadyNAS Duo V2, it's quiet and, as far as I can tell, running cool at a temp of 31 degrees C within my NAS.

I would definitely recommend this drive to anyone who wanted to install it into a home file server or a network attached storage device.

The one problem of concern I have was that the HD, though working properly, was not protectively packed well enough. The HD was in an appropriately sized box and that box was packed within another bigger package which contained two more ordered items. However, I feel that the amount of bubble wrapping used to protect the HD was inadequate, someone skimped on the wrapping which in turn put the HD at risk and so could still be shaken within its smaller box.

I have bought other OEM HDs before, from other suppliers, and their bubble wrapping was more than adequate.

I plan to buy another 2TB Caviar Green HD but I don't think I'll take the chance of the disk being damaged in transit by using Amazon's current supplier again.

UPDATE - 03 January 2013 --------------------------------

I took the chance and purchased another 2TB Caviar Green HD from Amazon, despite my reservations noted above, and for the knock down price of £70. And I must say that the packaging of this product was excellent, which is a far cry from how the first disk was delivered.

The packaging contained an outer box, filled with enough packing paper to absorb any bumps or rough handling in transition. The inner box, containing the HD, held the disk so firmly that it could not move about.
