While redundancy in a drive setup helps, it’s not really a backup and thus not a “safe” way to store important information on it’s own.
That said, selecting the way you setup a raid system is based on risk and utility. I have a raid1 with a hotspare for important files. And use raid5 with 3&4 drives for less important stuff. You can also optimise for reading speed for example (as the same file can be drawn from multiple drives)
