I read a blog post the other day that indicated mirroring was a much safe data redundancy system, because when you have to replace a drive, with mirroring you are only reading, which isn't as intensive on the disks as raidz2 where you are reading and writing to all the disks.
If I have 6 4tb disks mirrored, or 5 4tb disks in raidz2 giving me 12tb space either way, what would be the safest scenario for my data?
