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.
