Postgresql on windows / solid state

Good day all

            Someone has asked me now about this and I thought this to be the best place to get some answers.

                What they would like to know is whether there is a performance degration from running PostgreSQL on Windows in comparison to Linux.

                  Secondly, is it viable or worth it to look at Solid State drive as storage method instead of 15k sas disks for instance? What is the performance difference in this regard.


            Perhaps someone out there is running with this config or otherwise done some testing on it that can assist?
