What makes these SD cards stand out from the rest is that they are touted to have high reliability, high storage, and resistance to extended temperatures. This allows the SD cards to function in harsh environments just like the devices they will be plugged into (expect them to be use in rugged tablets, phones and notebooks). The cards will be available in 256MB to 8GB capacities, with read/write speeds of 20/13 MB per second. No word on when we’ll be seeing them on the market, but we’re sure professionals who need SD cards in harsh environments will welcome them with open arms.
