Checking to see which version of Synology’s DSM operating system is currently installed on your NAS may prove vital in ensuring you’re using the latest updates. Thankfully, doing so involves a few steps and requires a few moments since this information is readily available within DSM itself. This guide will show you how to quickly check your DSM OS version.

How to check DSM OS version

The version number will be listed next to “Current DSM version” with a link to the official Synology release notes. When new releases are rolled out, depending on your update settings, the Synology NAS is capable of automatically installing the latest version.

Otherwise, you can manually download the update from the website, and checking the version you have installed can prove handy.
