It depends on the access patterns. It's no worse at safeguarding data
than RAID-5 and can be better (some, but not all, combinations of
multiple disk failures will lead to no data loss, something which would
otherwise require RAID-6). It's faster at reads and much faster at
random writes. The cost: possibly quite a lot more spinning rust for the
amount of available storage. (For me, power-consumption considerations
led me to stick with RAID, though I've gone to RAID-6.)
