Customer Reviews

Best size/quality for your pounds
The positive reviews you read everywhere assure you this is a good product. From my experience, it's silent, fast and reliable. The best quality/size you can currently get for you pounds.

poor amazon packing damaged drive
be careful when ordering this item, with free super saver delivery it might be sent like my item was in a plain small cd/dvd/book packing carton from amazon and was damaged in transit and when posted in to my letter box it took a big drop shock on to hard floor denting the outer corner of the disk. i have contacted amazon regarding posting hardrives in this poor way and my only hope to other buyers is there took notice of my anger regarding poor packing and delivery of such oem harddrives (non boxed) in the post. diskdrives need care when delivered and not treated in the same manner as a book or dvd. these item need to run for a long time and hold very important data. amazon have kindly sent replacement item out and i do hope there packaged item better as there still sending with royal mail. if not it will be sent back for a full refund.

you have been warned...

WD 640gb hard drive
Like other buyers - mine was very poorly packed. However it worked OK. Amazon really need to consider the packaging of such items - common sense really.
