Memory cards such as Compact Flash (CF), Secure Digital (SD), USB flash drives, and many other form factors have become so ubiquitous, they are available just about everywhere, and have gotten to be amazingly inexpensive. It is not hard at all to find 2 GB cards for less than $20. However… as you start getting into the higher capacity cards (4 GB to 32 GB), you may find that some of the the more expensive cards are more than twice the price of the inexpensive cards of the same capacity. The question I frequently get from people is “Why are some memory cards a so much more expensive than others?”.
