Anecdotally we did some experiments prior to building our multi-TB search setup, where we compared local SSDs with remote (Isilon) SSDs. That setup was with simple searches and some faceting. I was a bit surprised that the slowdown was only 3x. I would expect the speed difference to be even smaller if the underlying storage is slow (spinning disks).

I don't understand the expected gain of adding replicas, if the data are remote. Why can't the replica Solrs run on the nodes with the data? Do you have very CPU-intensive search?
