"The cards can take the kinds of punishment that we often associate with rugged gear, such as temperatures from -13F to 185F, immersion in 3.3 feet of water for half an hour and the usual steep drops. It's beyond this that the resistance levels become truly exotic: the cards are also built to survive zaps of electricity, proximity to magnets and exposure to X-rays. If it all becomes too much to bear, the design will even fuse on the inside to prevent fire burning the card from within. Those who like what they see will only have to decide whether or not they want the SDAB range's 95MB/s read speeds and 80MB/s writes or are willing to settle for the SDUB line's respective 90MB/s and 45MB/s transfers.
