If you have a good RAID controller with battery backup for the
cache, and it's configured to write-back, this setting shouldn't
make very much difference.  Next time you're looking at hardware for
a database server, I strongly recommend you get such a RAID
controller and make sure it is configured to write-back.
 
Anyway, I'm glad to hear that things are working well for you now!
