The SD2/8GB is an 8GB Class 2 SDHC memory card. Class 2 means that the card writes at (a minimum) of 2MB/s. This is the lowest speed class you can get in SDHC. Don't let that stand in your way; this is an 8GB card after all. Kingston offers a lifetime warranty on all its memory products. You don't have to worry about it breaking, but if it does, you are covered.
