ReadyNAS Pro BE X-raid volume expansion OS 6
I am not familiar with X-raid automated volume expansion. The NAS currently running OS 6.10.6 and has three 10TB drives. When I created a volume, I think the only options were RAID 5 and RAID 0...

1. If I destroy the volume, would I be able to create a single volume X-Raid with three 10TB in bays 1-3 and two 4TB in bays 4-5?
Yes. (and the slot order doesn't matter).
What you'd have is a volume with two RAID groups concatenated together. The first RAID group would be 5x4TB RAID-5 (taking the first 4 TB of the three 10 TB disks). The second RAID group would be 3x6TB RAID-5 (taking the remaining 6 TB of those 10 TB drives). Capacity would be 28 TB (~25.5 TiB)
The easiest way is to use the "Perform Factory Default" control on the system->settings->update page with all the drives in place. This will reformat the drives, do a completely clean install, and create the XRAID volume described able.

3. Would adding the 4TB drives unfavorable for the NAS in terms of performace or future expansion?
No.
Thank you StephenB for the explanation!
I just initiated a new volume with all 5 drives and is in resync.
so is it correct that if I want to add a drive to the bay 6, or if I need to replace a drive (in case of a drive failure of one of the 10TB or 4TB) it would need to be at least 4TB? or at least 10TB?

You can either
- add a 4 TB drive
- add a 10 TB or larger drive
intermediate sizes (6, 8 TB) can't be added.
Of course if you add > 10 TB only 10 TB will be used (until you upgrade another drive).

Great. It will sync in two steps, so don't be surprised by that.
