Is there any reason to use those "extreme" cards the 30 mps cards? or a class 10 with the AG-HMC 150 or is a normal class 6 all I ever need?

Hi Randy

Technically you can even use a Class 4 cos they are rated in megabits per second so to get the bitrate in bytes your would multiply the Class number by 8. A Class 6 is theorically rated at 48mbs (6 x8) but it probably has a slightly lower sustained write speed but most certainly in the range of your highest cam bitrate!!

It usually has more to do with price!! I bought two new Class 10 cards as they were the same price as Class 6 ...however Class 6 cards are more than adequate but it doesn't hurt to have a fat safety margin on the card if the price difference is minimal!!!

o.k. good to know thanks for the input.
