Nowadays memory cards are fast and tiny, but they're also often flimsy and prone to damage. To remedy this problem, Samsung's created a line of cards in metal casing that are waterproof, shock proof and magnet proof.
The added physical security doesn't make the cards smaller, slower, or much more expensive either. The SDHC cards are Class 10-rated and come in 8GB, 16GB, and 32GB capacities. A 16GB SDHC card will run you about $US30, which is only a few dollars more than a true Class 10 card of the same size. (Note: Most cheaper cards are rated Class 10 but perform at the specification's minimum speeds, whereas these cards are faster.) If you're weathering difficult conditions, or just tend to damage your digital film, these cards can help you keep your data protected.
