a server typically makes very little access of the system drive once the 
OS and services are loaded...   sure, the boot time will be hugely sped 
up, but how often do you reboot a production server?

typically, the most important storage IO function on an application 
server is the database performance, and this requires a device with 
strong random write performance.
