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. In so doing the epoxy both makes the card extremely rigid and water-proof. Along with these extra protective measures you still get the same superb SDHC performance that's synonymous with the Hoodman name. The card's UHS-I (Ultra High Speed Class 1) rating and 300x speed rating enable read and write speeds of up to 45MB/s significantly greater than the SDHC Class 10 minimum of 10MB/s. When paired with today's high-end digital cameras or camcorders this guarantees an extremely fast and consistent capture of photo and video. The 16GB of data storage capacity provide ample room for storing your work and your memories.
