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 ;-)
