I don't think you understand the situations in which SSDs become cost effective. They are only really useful in high-access static database scenarios - for example, the database cluster that controls all the environmental variables for a weather modeling system. Or one that controls all the static data in a large MMO cluster. When dealing with high-write scenarios - like anything involving a cache (i.e. anything on an OS boot drive) - you are better off using a high-rpm disk. Put in a 7,200 rpm drive and get a nice 25% time reduction across the board. Not to mention the reduced life-cycle of SSD technology compared to magnetic media.
