I think the parent views on storage is still valid. Do not boot from the RAID volume where you store many terabytes.
I usually have a small mirror SSD for the OS (like 128G or max 256G). Those drives are super cheap, easy to replace.
For the /data I usually use ZFS or mdadm + xfs. Depending on the use case (for example do you want to add more capacity later? ) you can decide.
Using SDcards for server filesystem is negligent at the very least.
