I have used Kingston Datatravelers for years and have been very pleased with them. I am extremely pleased with the 8GB device which copies fast and completely when I back up files and folders. However, I laid out a bit of money for the 16GB model and I was sorely disappointed! It is horrible. Not only is it SLOWER than mountains wearing down but it only seemed to copy some of the files and completely ignored whole sets of folders in the copying process! I have gone through the process 3 times now and my plan is to do something we all would like to do with a piece of technological junk: slam it with a hammer. I have to wonder what the failure rate is on these high capacity Kingston crappers. It is basically useless. DO NOT BUY THIS 16GB MODEL. Check around on the net and see that many others have issues with this data drive.
