What tool can help manage and optimize a RAID array once it's set up?

RAID management software is specifically designed to manage and optimize RAID arrays after they have been set up. This type of software provides functionalities such as monitoring the health of the disks in the array, performing rebuilds when a drive fails, and allowing for configuration changes to enhance performance or data redundancy. Additionally, RAID management software typically offers a user interface that can help in managing the various settings of the array, such as adjusting the stripe size or migrating to a different RAID level as necessary. In essence, it plays a crucial role in ensuring that the RAID array operates at its best and can respond effectively to any issues that arise.

Other tools mentioned are not designed for managing RAID arrays. Disk Cleanup is a utility for removing unnecessary files to free up disk space. Device Manager is used for managing hardware devices on a system but does not provide specific RAID management features. Task Manager is primarily focused on monitoring system performance and running processes rather than managing disk configurations.
