It depends on your specific requirements - I'd start with calculating your
storage, IOPS and MBPS requirements and then configure the disk to best meet
those requirements.
If you need the storage capacity, go with RAID 5
If you're doing mostly reads, and can tolerate severe slowness in the event of
a failed disk, go with RAID 5
If you're doing a lot of PHYSICAL writes, or can't tolerate slowness with a
failed disk, go with RAID10
Don't worry about splitting out redo logs unless you need very high performance
DML and you have very frequent commits - and then you might want to consider
using an SSD.
