Query: not the best, but good enough.

I just did a quick and simple test. I formated and then proceeded with 1GB file transfer test, and 10MP camera continous burst shoot test on pentax k10d, 3MB/shot and 3FPS at MF mode. The transcend 4GB didn't write fast enough and did slow down after 25+ shots. I also have a cheaper A-DATA 4GB class 6 SDHC card and it can keep up until the battery runs out.The write speed is fast enough, but there are faster and cheaper 4GB SDHC cards out there. But for everyday use on my camera, it will work just fine.
