Kingston Class 10 128GB SDXC Card
 

The 128GB Kingston SDXC card has been evaluated to write at speeds above 14MB/s and read at speeds approaching 40MB/s. This is pretty good performance, but its by no means the fastest card. Serious photographers may be interested in seeing that write speed higher to ensure that their technnology doesn't keep them from getting the shots they want!
