I have a Kingston 256, a 512 is on its way. It works like a charm (after 3 days of constant data corruption that is). It may not be the fastest card in the world, but it really depends on personal preference. I am okay with the speed that it has already, I am not those kind of people who ask for the fastest write speed on a SD card! I mean, it depends on how you want to use the card. In my opinion, a fast SD card is only useful when used with a high resolution digital camera that requires SD. I don't know about you though.
