Re: physical layout w/ only 2 disks

If you do not duplex the redo log fles on separate devices, then you have a single point of failure.

If you do not duplex the control files on separate devices, then you have a single point of failure.

If this is a throw-away database, who cares.

If anyone depends on this database, then you must care. So, no matter what it does to performance, you must use both drives for both control files and redo log files.
