The card has performed in every way exactly as I expected it to, as an MP3 memory. I can't comment on how it would be in a digital camera or another device. So cheap and old technology it might be, as another reviewer commented, but the quality it good and if that's the case, then surely cheap is actually an advantage? If you want to use an SD card the same way I do but have the same capacity as a small iPod, then you'll need to spend a fair bit more and get the 1Gb version of this, but if you just want to carry a couple of album's worth of music for "emergencies" then I can highly recommend it.
I use this to play MP3s and it can hold about 8 albums worth easily.
I'd definately recommend the Viking memory, it's stable, fast and affordable. In fact, I think I'll buy another!
