AFAIK what mssql does against fragmentation is: it preallocates its 
tablespace in chunks of several mb/gb and then starts filling the free 
allocated space until it has to reallocate more. the fragmentation for such 
a single file (actually in most times 2 files for mssql) is practically 
ignorable.
