SanDisk Extreme USB 3.0 Flash Drive 64GB
Just bought one of these USB 3.0 sticks. It's a very nippy drive indeed. I saw a steady 200MB/s copying 24GB of AVI files into the stick! I've only got 16GB of RAM so I believe that's not cached and I was able to eject the drive immediately and all the files were there, so pretty fast!
