## Selecting the logical drive size

- If you change the RAID level of a logical drive, the total size (data plus parity) of the logical drive might change.

- If you do not use all available free space, you can create another logical drive. Click Add to do so. You can assign the same or a different RAID level to additional logical drives.

- If you do not want a specific logical drive, select it and click Delete. If the logical drive is in an array that is not currently selected, click the logical drive from the left tree. If the drive is on the currently selected array, you can select the drive by clicking its tab.

- You cannot delete the last logical drive in the array. You must have at least one logical drive for each array.

- Refer to the documentation provided with your operating system for information about the recommended logical-drive size.

- The default RAID configuration uses all available free space.
