Okay, I've been looking around all over the internet, and used MRoogle and could not find any kind of answer. I found some people say this and others say that. I'm wondering what the consensus is when it comes to SDHC card speeds. I'm getting myself a Canon Rebel XS kit for the holidays, as I've recently become fascinated by photography. It comes with the 18-55mm lens and I'm also getting a 55-250mm lens so I have some range, as recommended by a friend. I was looking at SDHC cards and I'm stuck between the SanDisk 16GB Extreme III and the SanDisk 32GB Ultra II. The speeds claim Class 10 / 30MB/s and Class 4 / 15MB/s respectively, though I think it's actually measured in mbps. I've read that speed is important in 2 instances, video - which the XS does not do, and burst shooting. I don't think I'll be doing much burst shooting, but I don't want to make that choice with a card and then be screwed if I change my mind in the future. I always like having the maximum possible storage space available, kind of an OCD thing. Which should I go with? Is the speed kind of overrated and the Class 4 at 15 "MB/s" will be fine for my camera?
