Assuming you meant to say on the disk array side or box side I'd say the
array side.  Hardware RAID is more efficient than software RAID because
the hardware typically has its own caching and CPUs.   

Having said that I will note that on most enterprise level systems
you'll see hardware RAID but ALSO see volume manager products.  On HP-UX
I've used both LVM and Veritas Volume Manager.  On Solaris I've used
Veritas Volume Manager and (yuck!) Solstice Disk Suite.
