You are here : Memory Cards > 2011 SD Cards
SDHC and SDXC memory cards up to 64 GB capacity are categorized as Class 6, 10, 16 or UHS 1. These standards equal a minimum write transfer speed in megabytes per seconds. However, our testing typically reveals pretty significant differences between various memory cards.
