I use a DS918+ at home which I got after having deployed Clustered RS units for VM storage in a previous role. The recent moves from the company (not certifying their devices with non first party hard disks, pushing more user licensed features (VPN/Email)) and a feeling that software quality is in decline (acknowledged bug in Apple TV app hasn't been fixed in at least 8 months).
It a real shame that both Synology seems to be following the ubiquiti route to smash their reputation to increase revenue.
