Hello everyone, The new Sandisk Mobile Ultra SDHC cards are out. So I've come up with the question: Do we really need to have up to 30 MB/sec? >>>ttp://sandisk.com/products/mobile1-memory-products/ultra-microsdhc-memory-card#features I've heard plenty of people say their 32gb with a class 2 or 4 rating is sufficient. But also, many have written reviews on Amazon and such saying this speed is slow. Money is not a problem I want the best. But if there's no need in paying extra then I won't. I plan to use it for 1080p video, photos, apps, and lots of music. The device will be Samsung Galaxy S II Epic 4g touch. Thanks for your help!
