Love my synology, I’ve been using it for 12 years now. I will upgrade at some point to latest 4bay version
Everything is fast thanks to an SSD and caching m.2. I max out 1gbit over SMB.
Snapshots have saved potential days/weeks worth of troubleshooting in total and is a must have. Cold backups are easy with Hyper Backup.
I couldn't ask for more.
