I'm not so interested in being able to use mismatched drives, etc, but I am interested in being able to create a raid setup with the enhanced data loss protection that this gives you. For a read-mostly system that doesn't need the extra read speed that raid5 gets you, its pretty compelling. With a 5 drive raid5 system, if I lose 2 drives, I lose all my data, while with this setup, I only lose 1/4 of it
