Well the archive process just copies redo logs to archive logs possibly multiple copies. You can always test that part as you need to.

Confused about your "the bigger users of I/O" statement ... log file sync is time critical for active transactions. Copying the redo logs after they switch just doesn't have that type of critical emphasis unless you are filling up online redo logs faster than you can archive them.
