To a point. A RAID 5 set will still have one filesystem unless you
partition the raid device into multiple partitions. Any filesystem error
will take out the entire set contrasted with individual drives which can
only lose that single drive. It's really a tradeoff any way you look at it:
RAID: One drive failure, no loss. One filesystem error, total loss
Storage groups: One drive failure, one drive lost. One filesystem erorr,
one drive lost.
