The website Digital Media Thoughts have published a comparative review of 4 different high-speed SD memory cards, testing which one is the quickest and how that relates to its overall value.

“In the realm of flash memory cards, most vendors offer two or more types of cards: the regular version, and a professional version that’s said to be much faster than the normal version of the card. I always thought that those “high speed” memory cards were something you could only take advantage of if you had a high-end professional camera, and that the extra top-end speed was wasted when used in a PDA, phone, or consumer-level device. Imagine my surprise when performing a test on a Pocket PC and I saw different numbers when using a high speed Sandisk memory card! This prompted me to do some further investigating, so I created a simple test to see how several cards from top vendors measure up against each other.”
