First time, on start, you MUST connect by VNC(i use tight vnc, raw mode picture) and choose install mode

Then - wait several minutes and try to find new nas by synology software. After that - install

 

I tried to use sda device for my HDD - it doest not work.

Also, tried to use file instead of raw device - it does not work.

Average speed on my platform is 40/25 write/read(strange) by samba on 3 cores/1024 MB RAM config
