Show me where that changes a plan.
 
No matter, the model for deploying SSD in conjunction
with Oracle is not meant for tablespaces anyway. The
primary focus for SSD is transaction logging acceleration.
 
Any shop that is languishing over redo writing latency is
doing so unnecessarily. The technology exists to 
serve up SSD via NFS to any large number of servers
in the enterprise. The model is NFS->SAN Gateway->SSD
and it is very very fast and supports extremely high 
bandwidth...and is OSCP certified...
 
Oh, yeah, I'm sure there is some Oracle glossy somewhere
that says ASM on round-spinning-thingies is faster than SSD...
 
:-)

        when dbms_stats.gather_system_stats is run then
        time to read a single block , and
        time to read multiple blocks at one time is
        stored is aux_stats$ table, which is used by the optimizer.
