I have a 64Gb Sandisk Extreme and when I try to record video sometimes it records but takes forever to save and sometimes it gives me a message that it isn't fast enough. Aren't these the fastest on the market right now?
Write speed is critical... I'm going to try this card with speeds up to 90 MB/s
