I don't know how Windows and NTFS behave but there may be some interactions at hand that cause problems.
A good example is Linux's ext3.
Under the default setting (ordered data mode), before commiting a segment of journal (every 5 seconds), ext3 commits all the related data.
This is very feature to have for applications that don't sync.
But it also lead to sync being a very expensive operation on ext3, not only from a thread/application POV but even from system POV.
