i just read "cheapest system" and "2TB of RAM" on the same line.
god i love this forum

this may be possible but speed is the question, you will be bottlenecked, depending on the speeds you are writing at which i am assuming will be crazy.
the raid controller would have to be top of the line.

then you need to worry about the life span of the SSDs....
if you are constantly writing to them at max speed, you will wear them out very fast.
and what happens when a few die? hopefully the system keeps on going.. but what about the data that was on them when they died.
