Rocky,
All defragmentation is accomplished via Microsoft's defrag APIs. In
essense, no defragmenter "moves" files around - it is the file system itself
that performs all file "moves" when defragmenting.
No special software is needed - you can even attempt it using the built-in
defragmenter. No difference between defragmenting a RAIDx volume and a
single hard drive volume. The file system fragments equally well on both
