Hoodman's 32GB SDHC Memory Card RAW STEEL Class 10 UHS-1 is a stellar storage solution designed to withstand the rigors of high performance photography and videography. While many flash cards can be on the more delicate side, Hoodman has included a few features to ensure that theirs is rigid and tough. The card is steel-plated with a hard plastic exterior. In addition, it contains miniaturized chip-on board technology, instead of a PC-board like many other flash cards. Because this technology allows for more space inside the card, Hoodman has filled that space with an epoxy, so that the sensitive flash components are completely secure and insulated. In so doing, the epoxy both makes the card extremely rigid and water-proof.
