I would be very happy to see mdraid within the Proxmox Bare Metal Installer. The reason behind this is, that I often have Proxmox VE nodes attached to a higb performance SAN or some other shared storage system. Often I don't even use the local storage on a proxmox node, but I'm very happy to see the node still working in case of a hardware/harddisk error. And this is something you can really nice do with a mdraid as local raid performance doesn't matter here.
My experiences on mdraid are ambivalent. While a mdraid provides very good stability, raid migration, easy maintenance and good throughput performance, I didn't get a low latency storage (means high IOPS) even on a RAID10 layout.
