Synology worked hard to give its DiskStation network-attached storage (NAS) operating system a refresh. DiskStation Manager (DSM) is the Windows 10 for Synology enclosures, allowing you to install apps and services, set up and manage accounts, configure various settings, and perform numerous tasks on the NAS server.
It has been some time since DSM has been updated with a major overhaul, but this all changed with DSM 7.0. The beta has been out since the end of 2020 and the general public will now see the update hit NAS enclosures. Here's everything you need to know about DSM 7.0.
Best Synology NAS
The DiskStation DS220+ is a well-positioned NAS with an attractive price and plenty of performance. The enclosure has two drive bays, an Intel processor, upgradable RAM, and full support for DSM 7.0 once it releases.
Synology DSM 7.0: New features
There are numerous new features in DSM 7.0, but we should first cover the important update notes. Synology has made some important changes to the update, which have been summarized below:
- USB hardware, including Wi-Fi and Bluetooth dongles, will no longer work.
- DSM 7.0 will end NAS support for ext3.
- DSM 7.0 disables NTLMv1 by default in favor of NTMLv2, which may prevent SMB clients from connecting.
- SSD caches on block-level LUNs are no longer supported.
- NT4 domains are no longer supported.
- DSM URLs have been modified. (Check firewall rules if in use.)
- iSCSI Manager is now SAN Manager in DSM 7.0.
- TLS/SSL profile level in Modern Compatibility will auto change to Intermediate Compatibility for better TLS support and compatibility.
- EZ-Internet has been merged with Router Configuration within Control Panel.
- Python3 has been merged into DSM 7.0 as a built-in service.
- The following DDNS providers have been removed:
- Dynamic DO!.jp.
- QuickConnect is secured with a Let's Encrypt SSL certificate.
- Security Advisor enables login analysis and custom account detection check items by default.
- Video conversion to FLV and MPEG-4 Part 2 formats are no longer supported on:
- Active Insight and Hybrid Share Service are built into DSM 7.0 and will be automatically installed.
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.
- Storage Manager:
- Added visuals of Synology NAS models with their drive slots, expansion units, and built-in M.2 slots to help users view drive status.

- Added the ability to require imported users to change their passwords after their initial DSM logins.
- Added the ability to assign user accounts from import lists to specific groups.

Synology DSM 7.0: How to install
I always recommend backing up your NAS before updating the DSM. Please do so before upgrading to DSM 7.0. You'll need to be running at least DSM 6.2 or above. You should see a notification for the update once your NAS performs a check in the background, but here's how to install DSM 7.0 on your Synology NAS manually if it doesn't show:
- Visit Synology Download Center.
- Select your NAS model using the drop-down menus.
- Change the OS Version to "7.0."
- Select the DSM version you're updating from, as well as 7.0 in the menus under the 7.0.
- Click on Download.
- Log into your NAS.
- Go to Control Panel > Update & Restore > Manual DSM Update.
- Click Browse and select the downloaded DSM 7.0 update file.
- Click OK to update DSM.
The NAS will then run through the installation process and will reboot. Sit back, relax, and read through the list of new features in the meantime.
