Synology (the company) are primarily known for their line of NAS devices. Frankly, I'm a fan of them. [Though that might be changing next time I need one](https://www.servethehome.com/synology-lost-the-plot-with-hard-drive-locking-move/). While personally I've played with self built systems such as [[TrueNAS]] or [[UnRAID]], if I have bulk data I want to store on premise, that I don't want to lose, I prefer to have an off the shelf system that won't be fiddled with. My DS918+ has been running strong for nearly 8 years now, with zero issues. I've deployed and used similar, newer, and more enterprise focused version of their equipment both for standard NAS purposes, as backup targets for [[Veeam]]. Used and managed perhaps a dozen of the things, with zero issues. Apart from one customer insisting to underspec a device and not use an SSD cache on an IOP intensive system with 80TB of data. But that's a problem with tool use, not the tool. The Diskstation Manager (DSM) operating system has been incredibly stable, and the wide variety of free applications Synology creates and maintains to extend the usefulness of the system is impressive. For example, while there are incredibly expensive software solutions for backing up Microsoft 365 data, Synology provides [[Active Backup for Microsoft 365]] for free on their systems. The inbuilt alerting and monitoring systems are robust and stable, and they are easily configured for SNMP.
