550D max write speed
« on: September 02, 2013, 07:41:35 AM »
I've seen it mentioned that the 550D has some limitations in write speed. I am thinking about getting a faster card but there's no use in getting something that is faster than the camera. Does anyone have any benchmarks or experience with the maximum write speed of this camera so I can get an idea of what to look for?

The SD controller's bottleneck is around 20-21 MB/s.
I'm using Sandisk Extreme pro series cards. The one marked 95 MB/s does the job right. With those i'm hitting the camera wall, not the card.
1200x496 @24fps for more than 20 secs is not a problem.
