One benefit of using storage level replication is that it doesn't
require much DBA work to do it.
But if your primary database crashes because of a block corruption in
a data dictionary table, then your DR site will have exactly the same
problem in it, doesn't matter how far away it is. With applying
archive/redologs to DR database you will less likely have this issue
(e.g. corruptions of primary database blocks due software failures or
disk controller glitches won't be tranferred over to DR).
