To me, the most important quality for a memory card is the write speed – how fast does the camera write a shot or shots to the card before we can take more. Based o­n the write speed data that Rob Galbraith produced, I've put together some tables which we can use when making flash card purchasing decisions. You'll also find the given retail price for each card, as listed o­n the B&H website.

In this short article, I've addressed some of the common questions about digital media and I've provided some useful data about card compatibility, speed, and price. The other factors, battery consumption and reliability will vary widely depending o­n your shooting style and how you treat your equipment, so I'll leave judgement about these factors to the reader.
