Suppose you have 3 Hard Disks (C:, D:, and E:), how you will distribute all your previous database physical files (redolog files, control files, and datafiles) on these 3 disks to obtain:

• Best Performance.
• High Availability for redo and control files.

You can check first I/O statistics
But best practice is create redolog groups have members in each drive
create control file in each drive
datafiles depend on I/O usage and high transactions
before you divide datafiles you have to make scope on High I/O of datafiles then decide how you can make the structure
