- Good security: Synology - albeit had a few set back - but has mostly pushed quickly security updates and had good security features by default (HTTPS, support custom CA, 2FA, etc.) which are on DSM and seems to be existing to on SRM!
- Good update track: I still have a NAS bought in 2011 which is still supported by Synology. This should be the norm, but sadly few manufacturer are keeping products up-to-date for so long. I hope Synology continue supporting in the next year My expectation is that SRM would have such excellent track record!
- Good user interface with advanced functions
PS: at the moment I own a Asus RT-AC68U. Asus seems to also provide regular updates and long support. But they do not seem so skilled in terms of security. This router I own is really good and is technically equivalent to Synology's. So the only reason that could make me buy the Synology would me VLAN support which the Asus does not have. It would not be wasting either, I good recondition the Asus as an AP and use the Synology as the only router.
