I am really impressed with the Kingston Data traveller 160 pen drive. Kingston have an excellent reputation, for reliability, quality and being competitively priced. This item lives up to their reputation. The quality is excellent and comfortable to hold, and it is definitely plug and play even for the xbox 360. The pen drive connection has a slide cover to protect it when not being used. I've been using the drive since Christmas and there have been no problems and no error messages. I bought it for the quality and fast read and write capability. This is a cheap way to expand your xbox memory and also for transferring saved games to another xbox when you are playing the same game, or alternatively just using it as a pen drive for storing and transferring files and images etc... I can highly recommend this drive and I would definitely buy another one in the future if I needed one.
Note to xbox users:
Using the latest xbox 360 4gb 2011: Xbox instructions recommend installing the latest xbox system software before using any pen drive. At present apparently xbox 360 can only use up to 16gb pen drives. Xbox 360 also requires any pen drive to be formatted to fat32 only, however the Kingston Data traveller 160 comes already formatted as fat32.
