processing extreme amounts of data at extreme io rates

For anybody trying to take that seriously, keep in mind that the Oracle's query planner is absolutely shit, the write performance can go to shit depending on the contents of your transactions, any advanced transaction insulation also destroys performance, and single-machine performance is completely shit, the extreme numbers are all on scalability and when compared to other (unpatched on the case of Postgres) ACID databases.

Also, it's not clear if those claims are still real, because you can only run Oracle databases if you sign a contract saying you won't compare it to other systems.
