If you haven't heard of ATP flash cards, you might be interested in knowing that they are high speed, completely waterproof, dust proof, ESD proof, and extreme temperature resistant. They also use Samsung SLC NAND flash components, the longest lasting, fastest flash in the industry. Their company sent me a 60X 512mb SD card to abuse just for fun. So I washed it in a load of clothes, popped it in the freezer for an hour and even put it in the dishwasher for a quick rinse. After all that torture, it still worked great in my Pocket PC. Of course, I didn't try the same thing with one of my other generic SD cards because I was afraid to ruin it. Click here to see why these cards can withstand all the punishment you can dole out. Retail price for a 512mb card is about $55.
