How to optimize pool in Storage Spaces on Windows 10

If you added a new drive, it's recommended to optimize the storage pool, and here's how using the modern settings and Control Panel.

Windows 10 optimize storage pool

On Windows 10, if you use Storage Spaces to store and protect your data from hardware failure when you add a new drive to a storage pool, it is always recommended to optimize drive usage.

The ability to run an optimization spreads existing data across the available drives, including the new one, to better use the space.

When adding a new drive to an existing storage pool, the process gives you the option to optimize it. However, if you cleared the option, or for any other reason, Windows 10 Storages Spaces includes an option to optimize a pool manually using the Settings app (build 21286 and higher) or Control Panel.

In this guide, you will learn the steps to optimize the storage usage of a pool for Storage Spaces on Windows 10.
