Hello!

There might be a difference in the performance but this totally depends from your application, the traffic and the overall memory usage.

However from I know the downgrade of the disk space is not a straight forward process. You’ll have to rsync the data to a smaller droplet using.

What you can do is to deploy the droplet while considering any future needs for your application and etc. In this way you wont need to increase/downgrade the resources of the droplet itself.

You can find more information about the downgrade here - https://www.digitalocean.com/docs/droplets/resources/downsize/
