Is a class 10 SD card enough for 550D 1080p video?
Title basically said it. I'll be shooting in 24fps 1080p, and plan on getting a 8GB card. People around the internet generally advise class 6 (minimum 6MB/s) as a safe point, but some of my professional friends say I need a 30MB/s speed, or roughly 200x, to ensure the buffer doesn't fill up during recording.
I plan to get a class 10 tomorrow, but unfortunately I can't bring my camera tomorrow. Would a class 10 be enough?
Update:Just in case you missed it, I'll be shooting on a 550D :)

A Class 10 is the highest you can get for an SD card. If you read your manual then you would see that it states that a Class 10 SD card is what's recommended to shoot video.
It's only CF cards that are measured as 200x or 30mb/s for example. For a 7D (which takes CF cards) then something over 133x is recommended, I would assume your friends use cameras that take CF cards. CF cards go up to 600x as far as I know (that's the fastest I own anyway) so there's a lot more variation to worry about.
With SD cards, your only options for a DSLR is Class 6 or Class 10. Class 6 is fine and will work with video but may not be as reliable (meaning, your camera could stop recording at any time because the card can't keep up with the data) so a Class 10 will be perfect. Nothing to worry about.
Yes
