Any tests on RAID-5 being slower than RAID-1 (a problem in software-raid
implementation?) ? I have always thought RAID-5 is the fastest... But I
suppose you will get a performance raise due to changing disks to more faster
ones (more volume almost always gives more speed, except for the cases when
that new volume is made by adding plates/surfaces/heads)
