(Disclaimer: I'm not using mdraid's RAID 5 or 6 at all so nothing to test or verify -- just curious).
Here a Helios4 user claims the way OMV creates an mdraid (not using partitions but the whole devices) will lead to lower throughput compared to manually creating aligned partitions first and then creating an mdraid out of the partitions: https://forum.armbian.com/topi…findComment&comment=69153
Any thoughts on this?
