- 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.
