[android-developers] open penalty
Is there a significant performance penalty for opening files on the SD card?
For instance, if you try to play a movie by opening 1000 PNG files in a directory on the sd card, is this way worse than having them all concatenated in one file?
My (probably flawed analysis) is this:
Since the SD card is not a hard drive, the 10ms or so seek penalty is not there. So, there probably isn't much difference.
Anyone have any other views?
FYI, I'm basically working on a hi-res loss-less movie player.
