The GoPro seems a bit finicky about card speeds since the last firmware upgrade I applied. The cards I've been using for quite a long time started causing it to randomly report errors and stop recording. I got a couple of these SanDisk cards and I've got the Hero powered via the USB port so I can fill the cards repeatedly without running out of battery. No errors reported so far, and I've completely filled one card twice and the other three times.I haven't always had the best luck with SanDisk but these are working well so far. Fingers crossed that they last a while, I use the camera to record off-road and &#34;brisk&#34; dual-sport rides.
