Hi, I'm eagerly anticipating my new evo soon and am wondering if a class 2 16gb card will be fast enough, or should I get a faster (and more $) class 6 card?
Thanks
To be honest get the fastest you can afford.
At 2MB/s transfer rate. Then you take a standard 720x480 movie and use handbrake to convert it to about 800 MB file.
That is only 400 secs of load time. The move is 5400 secs long.
To full bore the 2MB/s transfer rate, you would have to do a file size of
7,200MB. Or a standard uncompressed dvd.
Then at 4MB/s you would need 14,400 mb file, or the size of a blue-ray.
To max out a 6MB/s card you can go with a 21,000MB file. Larger then any movie file.
But if you are using any kind of good compression, a class two will handle most media you can throw at it.
To be safe I go with the class 4 cards. Class 6 and class 10 are nice, when you are using them for os's. But for media it is really not that needed.
I have class 2, 4 and 6 cards. And to be honest watching the standard compressed video you really do not see any difference.
If you want to record video from the phone then I would say the min. would be a class 4. But class 6 cards are really pointless. You would have to move more then 11 GB/hour to make it worth it.
Since you are watching only movies and music. There is no way you can watch 11 GB/hour on a phone.
If you like to play video games off the sd and listen to music, then get the class 4. If you like to run a video game, watch a movie, and listen to music, then get some professional help, but a class 6 will cover you until the pills kick in.
