There's plenty to like about the update, aside from the removal of USB device support for wireless dongles. The visual refresh to the OS alone is worth upgrading your NAS. After running DSM 7.0 for a few weeks, I've come to appreciate what Synology has worked into this release. It was easy to set up Plex on the Synology NAS after updating, and more.
The biggest change with DSM 7.0 is the user interface. The OS looks far more slick and modern, something you'd actually enjoy using in 2021 and beyond. DSM 6.x wasn't ugly by any stretch, but it was starting to show its age, especially as Synology competitors worked to improve their own OS solutions. Now, DSM is once again ahead of the game.
My favorite improvement is the login experience. Instead of using the username and password credential combination each and every time, you can now set everything up so you require only your username and a third-party authenticator. In the world of two-factor authentication, this is a fantastic improvement, and it even works with FIDO2.
Here's a full list of changes from the company.
Synology released update 7.0 for NAS enclosures on June 29. You can download the public release right now through your NAS updater or manually from Synology's website. See our full DSM 7.0 review for more details.
