I have a 1GB PQI SD card. I've had it for a couple months now formatted as ext3. It's been working fine and I've definitely been transferring lots of files to and from it. I got it from Fry's though, and also since those links don't work I can't tell if I have the same model or not. I've had a lot better luck with the PQI card than with SanDisk though, I can tell you that.
