Using raid5 will just leave you with reading from at least two disks
then writing to two disks instead of just writing your data to disk.
Unless write-performance is of no interest to you, you should re-think

If disks are pricey for you, just use all of them and deal with the
failed bricks. If disks are cheap, just put always two together in a raid1.

Have fun,
