+Again, a note to my future self and anyone else who might find this useful.
+
+I was annoyed by the fact that my NAS' disks would spin up every time I connected to the machine via SSH. 
+More than the noise and wear I hate to wait for the disks to spin up before I can do anything.
+
+I investigated a bit and found a solution that works for me on Ubuntu 22.04 LTS:
+
+Disabling the `Disk` plugin of `landscape-sysinfo` which is responsible for the disk spin-up. `landscape-sysinfo` is a package that provides the system information that is displayed when you log in via SSH.
+
+If you disable the `Disk` plugin, you'll lose the `Usage of /` info item and the warning if some disk is almost full. But if you're like me and don't care about that, you can disable it.
+
+Here's how you do it:
+
+First, run `sudo nano /etc/update-motd.d/50-landscape-sysinfo`<C />, then replace the line
+
+```shell
+"$(/usr/bin/landscape-sysinfo)")
+```
+
+with this one
+```shell
+"$(/usr/bin/landscape-sysinfo --exclude-sysinfo-plugins=Disk)")
+```
+
+No need to restart anything, the changes should take effect immediately for new SSH connections. The connection will now be faster and quieter because the disks won't spin up!
