Sd Card Real World Difference Between Classes.
This was mentioned a lot before the release of the Evo but I haven't seen anything since.
I just found my keychain camera and it's class 4 card to replace the stock class 2.
So far I'm simply restoring the files but I have browsed the gallery some.
If anything the class4 seems slower.
I'm transferring movies back to the card through the Evo and the tranfer rate is approx. 1.4MB/s.
The card is a 8gb Sandisk bought at RS last year.
-edit: It seems transferring more than one file at a time really slows it down.
Once one transfer completed the remaining increased to approx 6MB/s. The 1.4MB/s was two transfers combined.

Where the heck does my post keep going?
I tested both cars with that app in the same way for consistency, ran the test 3 times.
The class 2 card: 3mbs write, 6mbs read.
The class 4 card: 4mbs write, 13mbs read.
That explains the why copying the movies to the phone wasn't notably faster.
Doesn't explain the seemingly slower gallery performance.
I suppose that extra 1mbs could be useful for the camera. Better than nothing /:Evo4G. Now with more Internet.
