Be careful buying these drives! I've just bought 2 of these and checked their serial number on the Samsung site to see what warranty they have. It said, for both drives, "The product has been brought in from outside of this service region and cannot be serviced. Please contact your reseller or distributor."
This means that they are 'Grey Imports' and do not have a UK/European warranty with Samsung. Any problems and the first point of contact is Amazon.
On playing with the country selector on the Samsung site I found that of the 2 drives, one has a warranty valid till April 2014 in the USA, the other valid till May 2014 in Hong Kong. Obviously I purchased from Amazon UK, so they SHOULD have UK warranties!!
Could someone at Amazon please confirm the length of the warranty offered. I believe that it would have been 3 years from Samsung.
Also, I had to send one drive back due to it being DOA. Replacement was sent very quickly, arriving on Monday after the RMA being lodged on Thursday evening.
As always with any peripheral device, always allow it to acclimatise to your environment before you install. Sudden changes in temperature and sensitive electronics don't go together.
