Worked ! Thanks for fixing so fast.
Oh dear! I should have read here first instead of rushing to buy the 128GB Samsung SDD. Sigh! My 214+ play will not work too. 2nd day on my 14 days trial. Wondering if I should give up and just stick to Lumin or invest further in new NAS. 
Buy an item NUC and run ROCK
Unfortunately the DS214play won‘t work for RoonServer. It has a 32-bit os/kernel and 64-bits are required.
Is it still possible to return the SSD?
Getting a new NAS for the trial seems a little bit extreme to me.
There are also options to keep your NAS for storage with an Intel NUC as a dedicated RoonServer (ROCK) device.
But i‘d invest in new hardware for Roon after the trial.

Not a Roon issue but latest DSM seems to have broken my NAS. How annoying! I had everything working fine for months and now the NAS just drops off the network at random and only way to reconnect is to restart it. I shouldn’t have updated and rolling back seems to be not a simple thing. Anyone else had problems? I have a 916+
No issues thus far on my DS1515+ running DSM 6.1.4-15217 Update 2. I believe the latest updated fixed security flaws in Samba, which might affect your network access if your core is running on a separate machine. If this is your configuration, is the minimum SMB protocol still set to SMB2 or higher under the File Services setup (Advanced) in Control Panel? I have Room running directly on the NAS, so Samba file shares are not involved in playback since the NAS shares are seen as local drives in my setup.
Thanks but Roon core is running on the NAS as a package. The NAS drops off the network at random, I can’t see it in finder on my mac until I reboot the NAS. I only use the NAS for Roon and music storage and photo backup so I don’t notice it until I need to use Roon. Tried searching under Synology forums etc but no clues. The fact that it appears to happen randomly does not help as hard to troubleshoot. Didn’t realise there was an update 2 so I just did that one. Will wait and see if it happens again.
