Maybe not as fast as a German RUF creation, the Buffalo RUF2-RVS series USB thumb-key has nothing to be ashamed of. Available in 4GB, 8GB, and 16GB, the SLC type memory card achieves transfer speeds up to 38MB/sec… If you want to make a little compromise on speed but need a larger capacity USB Key, you should consider the RUF2-LVS Series thumb-key that’s available up to 32GB but with only 30MB/sec in data transfer speed.
