I'd say as much as we shuold trust that checkbox in the Windows settings
page...
I haven't come across a case yet where it doesn't work, but that doesn't
mean there isn't one. It certainly writes through the writeback cache of
shiny expensive raid controllers :-) And it does write through the IDE
drives that I've tested.
Bottom line is, I think that the cases where fsync_writethrough doesn't do
it, that checkbox isn't going to work either....
