*REAL* slow: I consider anything under 20MB/s slow.
But where did that number come from? The pattern of reads will make a
*huge* difference...

I think you might want to have a better idea of what is going on first
before you just start throwing hardware at it. If your numbers were
correct but still too slow I'd say sure. But your numbers are *broken*
wrong. You *might* fix your problem (by accident!) by throwing away some
pieces and adding others, but you might not, too. Then you've got a
client that just spent a bunch of money for nothing...
