Another assumption behind XFS is that storage is the best quality and therefore it does not lie when it reports back that the data was flushed all the way to the magnetic layer (which is something that cheap IDE drives/cards lie about, sometimes).
Is IBM/Hitachi Deskstar known to not lie about the flush?
I am almost certain that I've seen a free software tool on the Internet a while ago that did exactly this: it could tell whether the hard-drive and/or the controller lie about flushing the data all the way to the magnetic platter. I think the technique involved yanking the power cord or hitting the reset button (different failures, perhaps it's worth testing both) while the software was doing some complex read/write operations with the disk. After reboot, the same application looked at the disk and could tell whether the data was properly flushed or not.
I can't remember the name of the software or anything, but I imagine that a clever google search would reveal it.
