Don’t get me wrong here. Having more capacity is always a plus, but 16GB of space?! I can barely fill up my 8GB SDHC and Kingston comes out with a 16GB Class 4 SDHC memory card. What does Class 4 mean? Well, the minimum data transfer rate on this is 4MB/s. Not too shabby. That’s about all you really need to know, too. It retails for $231.
