<cking> xivulon: ext3 journal writes will be flushed straight through to the device if ntfs-3g has the -syncio mount option. However, if you want extra resiliance to make sure writes get flushed immediately then I recommend -o sync on the loop too

<cking> It's a kind of performance vs reliability tradeoff

<xivulon> any idea of the performance hit for that?

<cking> My tests showed -o sync on the loop was 1/3 to 1/2 slower. But I did just raw block write tests using dd. Normal usage may differ.
