I bought this card for my fujifilm F10 camera. Sandisk is very reputable, so no reliability issues so far (been 3 months). I don't expect it to have any issues on that respect. But I am dissapointed with the speed of writes (close to 2-3secs per write at 6MB resolution) and reads (more than 1 sec/view). It could be a problem with F10, but I really doubt that. The camera supplied fujifilm 16MB XD card was much faster to write to and read from.
If you let the pictures sit in the SD card for long and then transfer them all at once using the USB (2.0) connection to your PC, be ready to give yourself an easy 15 to 20mins!!!
May be this is not SanDisk problem, it is the XD format problem, but I have no way to figure that unless I test many other XD cards, particularly the ones from Fujifilm.
