(3*3+1*1+1*3)*1000^4/1024^4 = 11.82 TiB
Allow for things like the root volume, swap partition and overheads and you'd get 11.81TiB.
You've got a 4x3TB layer, a 2x1TB layer and a 2x3TB layer. To get the most expansion you would've needed to add the 4TB disks before the 6TB disks not afterwards. You could replace the 4TB disks with 6TB disks done the track to get further vertical expansion.

This makes sence and answers my question why i have not seen this on my other readynas. On my other readynas i have always increased the space from disk 1 to disk 4 by 1TB each time.
Than you
