The problem is that the average developer doesn't expect the fs > to _re-order_ stuff. This is how most common fs did work long before No it isn´t. Standard Unix file systems made no such guarantee and would write out data out of order. The disk scheduler would then further re-order things. If you think the ¨guarantees¨ from before ext3 are normal defaults you´ve been writing junk code
