I do know that my MVIII uses a hack of a lot
less power booting off a
remote disk than it did spinning up 3 MFM drives. I can only assume
that the RAxx use even more juice.
Dunno about anything as new as an RA9x, but the RA81 draws 30A surge
current (which is why they have that daisy-chain power sequencer port),
and 8A steady-state. That's a big honkin' motor in there, plus several
square feet of controllers.

I have a couple of RA70s. I have yet to power them on. I would like
to find some in-cabinet SDI cables first (lightweight ones; I have
several of the big, black rubberized ones). My goal is to put them
in my BA123 and get away from the RQDX3. If I thought I had enough room
in a BA23 for the KDA50 and enough cards to make it worth the effort,
I'd consider that, but between cabling and power consumption, I don't
know if that's a good idea. OTOH, they'd be *great* with an 11/750...
finally the CPU would suck more power than the disks (mine has a Fuji
170MB drive, a Fuji Eagle, an SI9900, and an RA81).
I am _not_ shopping for any RA9X drives (but even one would be a lot
better than a rack of RA81s ;-)

I know for a fact that there is a *large* difference in the power
consumption.
