To my mind, the only thing you should put between the filesystem and
the raw devices is RAID (real-raid - not raid0 or linear).

I believe that implementing RAID in the filesystem has many benefits too:
- multiple RAID levels: store metadata in triple-mirror RAID 1, random write intensive data in RAID 1, bulk data in RAID 5/6
- improved write throughput - since stripes can be variable size, any large enough write fills a whole stripe
