Just to add a little bit to Ekrem's comments.

If there's anything where you want redundancy, then it is the log files. If you lose the mdf file,
you still backup the log, and have zero data loss. If you lose the log file, well, you can't do a
backup of the log...

Of course, above assumes full recovery model and that zero data loss is something you aim for.
