Update from 15.1 to 15.3 failed.
Update from 15.1 to 15.2 worked.
Update from 15.2 to 15.3 worked.
Update from 15.3 to 16.0 worked.
So my test with a single 750GB came out pretty fine. The interface ist fast, the transfer rate, too. Even the cooler is quiter than in Lacie original FW.
I'm now going to upgrade the capacity from 2x 1,5 TB to 2x 3 or 4TB in the next weeks.
The console is a great great tool doing al the partinioning stuff and establishing an excellent base for the future.
(it also worked in a Fritzbox environment with IP range 192.168.178.xx)
Big thanks to this well done job you did !!
