I created 4 x 60GiB virtual disk. Three of them were merged in one mergerfs disk with policy: Most free space. I configured snapraid with the same 3 data disk e 1 parity disk. Then I copied about 30 GiB of files inside the shared merged disk. Then I made the first sync.

Snapraid offers a pretty good compromise solution, with much of the same flexibility but with the added benefit of being open source and not bound to a particular distro.

During the sync Snapraid will report a sync speed of 400MB/s because that's how much data it is crunching through. If you take the same 200GB files and write them to a single disk (ie your array is not balanced), then 200GB of parity must be written. Now it will take 4x longer.
