Suggestion for x-raid3
This is a suggestion for a hopefully smarter utilization of disks-arrays of disks of different sizes. Say that I have 3 disks of 1 TB each. I buy a 3 TB disk and put it into the empty slot, after s...

There may always be a more optimal redundancy setup based on a specific combination of disks but X-RAID2 is not designed to be always the most optimal from a volume capacity perspective, it is designed to be expandable (X-RAID = eXpandable RAID) but without putting your data at risk during the expansion.
Considering that and your original 3 examples:
The 1st scenario is a unique case that only works when the 4th drive added is 3X the capacity of each of the other drives - it is not expandable to other disk combinations and so changing one of the 4 disks would require a complete restructuring of the array and so putting your data at risk which is contrary to the aim of X-RAID.
The 2nd scenario, your understanding of how X-RAID treats that configuration is wrong as the NAS already accommodates that type of configuration as @mdgm describes in the post previous to this one
The 3rd scenario, your assumption that the volume capacity will be decreased is also wrong - that never happens as what would you expect to happen to the data already on there?
