There are basically two different classes of storage types:
+File level storage::

+File level based storage technologies allow access to a full featured (POSIX)
+file system. They are in general more flexible than any Block level storage
+(see below), and allow you to store content of any type. ZFS is probably the
+most advanced system, and it has full support for snapshots and clones.
