Given the wear patterns seen in corporate RAID boxes it is clear that some redesign is needed.
Modern SSD products have a controller and they are fully programmable. By maintaining a table of writes a SSD can managed to reduce the writes to a given area to minimize the possibility of a cell failure.
Leveling out the writes can double the service life of a given SSD easily. Wear leveling benefits consumers and corporate users alike. The advantage is so strong that destructive testing sometimes can be 10x the guaranteed write tolerance.
Using a SSD is best with Windows 7 which supports the TRIM command so that a given SSD product is optimized.
