# SUS 4 How do you take advantage of data access and usage patterns to support your sustainability goals?
<a name="sus-04"></a>

Implement data management practices to reduce the provisioned storage required to support your workload, and the resources required to use it. Understand your data, and use storage technologies and configurations that best support the business value of the data and how it’s used. Lifecycle data to more efficient, less performant storage when requirements decrease, and delete data that’s no longer required.
