Not nearly as much as you would expect. For the price of the SSD and a
SCSI controller capable of keeping up to the SSD along with your regular
storage with enough throughput to keep up to structure IO, you can
purchase a pretty good mid-range SAN which will be just as capable and
much more versatile.
