Hi,
    We're considering changing from RAID5 to RAID0.  Info:
Solaris 5.8
TSM Server 4.2.1.15
Storage array 21 36Gb disks (currently RAID5.

Is this a wise move?  If we make the change, any recommendations on the
stripe setting?  Default is 64Kb, but it can be set while we
configure...  Performance seems quite slow with RAID5 and we have  a
development box we're going to throw this at.  Any thoughts or
recommendations are much appreciated.
