Q: Is there any speed difference between standard and Ultra cards when used in a PDA? A: Not much – you'll see a twofold difference in raw read/write speed at most. If you plan to use these cards in other devices (especially in high-speed, high(er)-end digital cameras), you should get the faster version, though.
