Every man is a borrower and a mimic, life is theatrical and literature a quotation.
- Ralph Waldo Emerson
Quite possibly one of the more confusing counters at the camera store—or sections of a website as the case may be these days—is the area full of Compact Flash and SD memory cards. It’s easy enough to tell the cards apart by capacity, but what about speed? What the heck does 45x or 300x really mean? And are some brands really better than others? It’s all just memory anyway, isn’t it? Can’t one just get the biggest capacity card for the least price and call it a day?
