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.
How to optimize storage pool using Settings

Select the storage pool to reveal the available options.
Click the Optimize button.Quick tip: Alternatively, click the Properties button and then click the Optimize button.
Once you complete the steps, the process will begin spreading the data across the available drives participating in the pool. Depending on the amount of data, this could take a long time. As a result, it is recommended to run this option when no one is accessing the storage.

Open Control Panel.
Click on System and Security.
Click the Storage Spaces option.
Click the Change settings button.
Under the storage pool, click the Optimize drive usage option.
