Probably the cheapest way, at the moment, would be to use a RAID for
data storage and a SSD as a "fast disk" containing application code
and a cache. Write data to the cache and use a daemon running in the
background to write cache data to RAID during low CPU usage periods.
It might also be possible to use some sort of memory cache, write that
cache out to SSD cache. It might let an application run full bore
without waiting on write-to-disk at all.
On the other hand, you'd be writing a DOS system
