For our SDI and DSSI solid state disks, most of the usage has been where
the disk access paradigm and the nonvolatility of SSD is important. 
Most of the systems have been transaction processing systems of one sort
or another.  Examples include financial trading, order entry and
inventory control, and telecommunications (700, 800 and 900
translation).

Another thing that these have in common is that they justified the expense of 
SSD based on the business result (more financial trades = more $$$) rather than
the price/performance comparison to magnetic disk.

If the application supports putting the data in main memory (or you have a 
RAMdisk driver available), and the volatility of main memory is not a problem,
by all means main memory is a higher performance solution.
