BitCoin doing insane amounts of I/O operations

[Pas]

Hello,

I'd like to request an enhancement for the possibility to turn off fsync()'ing. (In case the excessive I/O is not because of fsync, then it just needs more caches.) Yes, my computer can handle it, but it just ineffective, noisy (yes, the HDD is constantly scratching) and there's no point in doing it (any lost block can just be re-downloaded from the CoinCloud). It should fsync() only when it has found a hash.

Thank you.
