I think I can go with the "throw more hardware (bigger disks) at the

boost to the read performance, in theory.
I need to do some tests and figure out what works best in this
particular case.
IMO, you do *not* want RAID5 there. RAID10 is likely to work best.
With todays larger drives, and the amount of time raid5 rebuilds can
take leaving you exposed to double failure, and the price of drives, I'm
not sure there's _ANY_ application anymore for which raid5 is
appropriate. And absolutely for sure, anything involving SQL databases
should be raid1/10...
There's not much room in the system, it's a 1U. I think I can fit a
full-height card in it, but it must not be too bulky.
the cache battery backup option might be tough to squeeze into a 1U.
