there must be a pci sata controller on the solaris hardware list...
lsi chipset?

" As for power savings, all you would save would be the power consumed

" much power as a similar modern system, but running a handful of 1 TB  
" SATA drives would consume much less power than larger number of

" forklift upgrade, you could see some serious power usage reduction,  
" but I agree using that as a cost-justification is probably a weak  
" argument.

yeah, but -- those 73G drives could be in a raid5, so that if you lose
one you lose nothing, but if that replacement 300 goes...

if you have enough data to fill a rack of 73s, replacing them with a
few 300s in a raid would be imho better than a single 1T.
