That is not the answer your are waiting for but...

IMHO, once you overcome the mythical concept that a database server will always perform slower than a direct file access then "Spatial is not special anymore!" [who said that?] and you can think on the benefits just like a banker or an accounting bureau. Database servers in general are capable of making a good use of the available resources. For raster what is needed is a good BLOB support with cursor preferably. Spatial extension and schemas are indispensable accessories, they should provide metadata, georeferences definition, spatial indexation, etc. but they should not drag down the performance.

Just my two cents.
