Again: In FAT/NTFS world, a file counts as not fragmented if all fragments are 1MB or larger. Defragment tools normally don't touch such files.
At a 300 MB WBFS drive, the block size is 8 MB. That means the smallest possible fragment is 8MB. This is about 1000 times the block size of a FAT system. If a 4GB game is really fragmented into 10 peaces (happened never at my drive), then we have an average fragment size of 400 MB.
At the moment I use 2x 320 GB WBFS partitions for my 2 Wiis. The disk usage is about 50% and *all* games have exact 1 fragment. And I replace weekly images because of testing MKWii custom tracks. But WIT will always search the ideal place at the drive.
And here is the memory layout of one drive. I use it since May 2011 (first insertion date). Watch out the repeat factors at end of the lines.
