sync mount option makes writing *very* slow
I noticed today one of my external HDDs was writing at 1MB/s, and another at 2MB/s, but both were reading just fine. I've just tracked down the problem. I have been mounting USB HDDs with the sync option, so sudden power loss / disconnection / whatever doesn't cause data loss, however, it had quite an effect on speed. Removing the sync mount option boosted write speed up to 47MB/s.
Is this known/expected/normal behaviour? I'm using 2.6.33.2-1 from testing.
