On a server, I have 3 SATA disks.
I’d like to create a root partition in RAID 1 of 50GB and a data partition in RAID 5 with the remaining spaces on my disks.
There would be 2 different RAID types on the same disks.
Would it be an issue if one of the disks fails? Is it better not to mix RAID types on the same disks ?
This would definitely not be a recommended setup for a business production system: It adds pointless complexity while unnecessarily increasing your I/O overhead.
