One case against using partitions on mdraid: if your array gets messed up, you get to recreate those partition tables yourself and that's just hilarious if you don't have a backup. Happened to a friend of mine, reason was a UPS brownout. I think he scanned his disks for copies of the superblock but didn't find any and then somehow with a lot of hassle eventually figured out what the partition tables were. So in a catastrophe, partition tables are one more obstacle to cross before you can start actually recovering your data. My only mdraid was on raw partitions but that never had any issues. I think zfs effectively does the same, no partitions.
