Does anybody know what the read/write speed to a SD card is on an ipaq 4155? (or where I could find it). If I bought an SD card that was advertised as 60 x, and up to 9 mb/sec, would I just be wasting money? The card in question is here.

I can't speak to the actual read/write speed of the 4155. But... keep in mind that transferring through ActiveSync to the SD card is always a slooooooooow process. If you use a card reader to transfer instead, you'll see a huge improvement. You won't have your Pocket PC, ActiveSync, and the various other pieces involved slowing things slow.

I guess it all depends on what you are doing and how you plan on transferring data. There aren't a lot of apps that are going to benefit from memory card speed on the Pocket PC.

Over ActiveSync, you'll only see some 120-180 kbytes/sec transfer speeds, which is orders of magnitude slower than the speed in a USB2 desktop card reader/writer. Solution: get a separate card reader.

Furthermore, you won't benefit much from having a hi-speed card in you PDA: current PDA's access even the fastest SD cards at the maximal speed of 1.5-1.6 Mbytes/second, which is 2-3 times more than the speed of accessing no-name cards (500-700 kbytes/s) under the same circumstances.
