Defrag SCSI RAID 5 Setup

Are there any problems/disadvantages in defragging volumes that are on a SCSI RAID 5 setup. Is it recommended or not?

Can't imagine any - you want defragged files for faster access.

Good question though as there is some suggestion that these donot require defragging.
The Operating System treats a RAID as a larger capacity hard drive, but defragmenting the RAID may not improve the performance.

To prevent Disk Defragmenter from moving files to bad sectors of a disc run the Error-checking tool before running Disk Defragmenter.
 
Disk Defragmenter rearranges the files and free space on your computer so that files are stored in contiguous units and free space is consolidated in one contiguous block. To access the Disk Defragmenter utility, choose Start > All Programs > Accessories > System Tools > Disk Defragmenter.

FYI
The hard drives should match in size and speed. All drives in any array should be identical models with the same firmware versions. RAID can be used with any size drive, however only the smallest drive will determine the usable size of each drive in the array

FYI, the hard drives DO NOT NEED to match in size and speed.  Major vendors routinely ship replacement hard drives that are neither the same firmware nor the same model or sometimes even the same size.  It is  often recommended that they are the same size, brand, and speed, but strictly speaking it is not necessary.  The RAID will perform as if the array consists of the lowest spec components.
