And it's responsible to run this type of programs that do so many writes in the emmc??
Can't the flash memory wear out too quickly with this?

I have a small server at home (SheevaPlug), downloading torrents all day, and after a few weeks I had some bad blocks in my SD card, anyway the problems seems not to be increasing...

Anyway, I would run transmission in mircroSD so if it gets broken you would be able to change it
