I bought my Fuji 512Mb SD memory card from a cut-price major supermarket out of necessity while on holiday (my 256Mb card was full!), and it works fine in my camera.

However, the fun starts if I use it in my PDA. I have a Palm Tungsten E which I use as an MP3 player, and my preferred method of getting tracks onto the card is via a card reader, as it's quicker than syncing via the PDA. This is OK when data is initially loaded onto the card, and it works fine. The problem is when I eject the card to load up a new track, as the PC shows it as being on the card and all hunky dory, but when it goes back into the PDA - lo and behold, the entire card is corrupt (eg, I usually have 2.3Mb of 7.2Mb free, as the other 500Mb is there but unreadable). This is a real pain, and only happens with this card. I don't know if it's the Fuji card or the Palms inability to handle cards bigger than 256Mb, but I'm really fed up with it.

I'll give it 4/10 because it works in other devices for non-MP3 purposes.
