I already drop my cash on the Pretec SDXC 64GB cards but if you didn’t pull the trigger, B&H is having a hell of a good sale on the Sandisk 64GB SDXC cards. You can check out my earlier test results on the smaller capacity Sandisk Class 10 cards here, although the Sandisk was a little behind the Pretec card in the speed department, the Sandisk card still performed quit well. I’m sure these cards will sell out quick so if you’re in the market for a large capacity SDXC card Check out B&H’s $48.95 Sandisk 64GB SDXC card sale before they sell out.
