After sending a few messages back and forth about camera memory readers, I thought I add a few thoughts about the memory for digital cameras.

I have found that a lot of people don’t think about memory speed when it comes to digital photography. And, quite often, it's too hard to tell. I have found that even memory (compact flash in my case) that claims to be "Ultra" or "High speed" is only 4x. I just purchased a memory card that is 33x and it makes a big difference in my case.

However, I shot hundreds of photos in rapid succession at 5 mega pixels each. You may not need something as fast as 33x read speed (27x write), but you can usually get something faster than 4x for the about the same amount of money.
