This is the fastest MicroSDHC I've used.  I got it for a tablet but it turned out the tablet had no MicroSDHC slot when it arrived.  So, using it for a 10.1MP camera.  It writes very quickly and then off to the next shot.  I'm quite pleased with the performance of this card.I think there may be cards even faster.  But this suits my needs of casual photography.
