+Standard C storage routines are not efficient if a single, but fast stream of 
+data have to be written on the disk. The fastwriter is optimized for this use
+case. The following methods are used to speed-up writting.
+ * Linux AIO is used to avoid intermediate file caches
+ * The large extents are pre-allocated and the file system is hinted that more
+ data will follow  
+ * For XFS volumes, the real-time mode can be used
