I don't have a sense for the compute power difference between a 1GHZ ARM and 1/64th of a Quad Core Xeon or whatever a VPS represents. But I also am continually surprised that SSDs are still independent devices. I'd expect at least Apple to have integrated one on the mother board by now. This idea is predicated also, in part, on the assumption that there's some software that will allow part of the SSD to work as a cache for the networked hard drive.
