Could be the camera buffer rather than the card. I know my D7100 is renown for having a poor buffer. I only shoot in single shot mode so it's never bothered me.

The continuous shooting rate of the 600D is one of the biggest distinctions between it and the more expensive 60D (along with its smaller viewfinder and single dial control, etc). It attains a respectable, though not exactly blistering 3.6 fps in all its image modes, but can maintain this for just three frames in raw + jpeg mode, and 6 frames in raw only. Because it takes 8 seconds to fully clear its buffer in these modes, it's not terribly useful for shooting short bursts of action, since there's every chance the camera won't have recovered by the time you need another handful of shots. If you find yourself trying to shoot sports or action, you may find yourself better-off taking a metering and WB test shot then shooting JPEG, which gives a much more respectable 40 frame buffer.
