Defragging a RAID 5

Simple question... perhaps a more complicated answer:

Is defragging a RAID 5 array good, bad or a useless waste of time???

My guess would be that it's a waste of time because of the data scattering nature of RAID 5.

No Jared - your guess is off the mark :(

The striping is done at a hardware level the OS has nothing to do with it, de-fragging deals with the storage of "non-contigious" files that are split up because of the way files are stored at a cluster level that is handled by the file system of the drive NOT the type of volume/partition

I didn't say the OS had anything to do with it.  

I stated that with raid 5, or raid 0 for that matter, the data gets scattered all over however many drives you have.  I don't see what good a defrag would do.  It seems to me that a defrag of a RAID 5 stripe set would just move pieces of files or pieces of directories around the raid array.  Is there even such a thing as "contiguous" with RAID?

Should I get something special to defrag it with, or does the windows defragger or even disk keeper light work OK?

Jared
Nope - disk manager and defrag is all you need :)
