I bought the same one. There's even room for 2 nvme ssds, which is nice for caching, or faster time machine backups. Works like a charm with near zero maintenance. Big fan of the drive sync client, too.
The only "maintenance" bit we encountered was the need to replace drives. Not a huge deal, but Synology does a good job making you feel like you are a terrible NAS parent when that happens 😂.
