Lexar's 4GB SHDC card isn't the first of its kind to be rated Class 6 for speed - Transcend won that accolade in October 2006 - but it's no slouch for that. Class 6 devices have a guaranteed minimum data transfer rate of 6MBps, and Lexar said its card has a minimum write speed of 20MBps - hence the 133x speed.
