defrag over hardware RAID5

Is there any logic to defragment volumes residing on hardware RAID5?

From my understanding should be no benefit because the file blocks are
anyway stripped to different hard disks and the read/writing process on them
is mostly random controlled by the hardware.

Thank you,

There is some benefit. Generally a few percentage on the maximum
throughput. If the machine(s) is lightly loaded, you probably won't notice
a difference.

Chris,

The file system has absolutely NO idea of what disk technology you are
using (IDE, SCSI, RAIDx). The file system fragments - it happens regardless
of disk technology.

Defragmentation (which occurs at the file system level) ensures that only 1
logical request has to be made to access a file - regardless of where that
file is physically found on the drive(s).
