5 The best micro-SDHC card for speed and reliabilityRoughRider | 28/07/2010 | See all RoughRider's reviews (4)I have owned many "cheap" SD/SDHC cards. Most suffered from slow transfer speeds (both read & write) and half of them broke after removing/reinserting them many times.This Samsung card may cost a litlle extra, but in comparisson it excels in transfer speeds and toughness. My guess is that the only way you can damage the card is if you do it deliberately. There is none of the flimsiness of lesser cards. Transfer speeds are also superb. This card reads twice as fast as my previous card and writes 4-6x as fast.
