Then you'd need a bunch of 10K RPM hard drives, each with 16MB or more of
cache. You'd have to specifically NOT RAID them. That is, if you want
"top performance". To me, "top performance" means fastest that the system
can run without undue risk of data corruption. So no RAID, regardless of
type. Either it'll slow you down, or make it more likely to lose your
data.

There are faster things to use instead of HDD:

If you need fanout, an Areca with 16 SATA ports would be one
way to connect a whole bunch of them. Just set it to do RAID0
across all 16 :-) Makes a nice 64GB disk, even if the controller
on the Areca slows it down a bit from its 2.4GB/sec theoretical
max. Even the PCI-E x8 interface is only 2GB/sec in one direction,
so you wouldn't get all the speed available on the SATA ports.

AFAIK, the IRAM doesn't need to be plugged into a PCI slot.
It just draws power from the slot, and doesn't use the PCI
bus. I don't know what voltages it requires, but a little
careful soldering and some wiring harnesses, would solve the
problem of providing a home for 16 of those cards.

At $100 a gigabyte, you'd get change back from a $10000 bill :-)
Sounds like a fine home project.
