But if you have enough RAM that the entire DB can be held in RAM, and
if the DB acess pattern is 90% read, 10% write (which is usually the
case) then do you really need to worry about disk performance?
It seems like for most applications, it is possible to hold all the
data in RAM, and RAM is cheap these days.
