You will need to factory default your Duo and switch to Flex-RAID 0 mode. This will allow you to use each disk independently with a separate volume on each disk. Switching RAID modes requires a factory default, meaning that all data and settings will be lost. You would need to backup your data and restore.

After performing the factory default, the NAS will default into X-RAID after 10 minutes. In order to configure it for FlexRAID, you need to connect with RAIDar before the 10 minute window expires:

By default, FlexRAID will create a RAID1 volume which you will need to delete if you want to create a RAID 0 volume. Then, you can follow the instructions here & create your desired volume type & size:

Be advised that if all of your data is stored on the NAS it is not really considered a backup (even if you have a separate copy on the other drive). Hardware failure, multiple disk failures, accidental/intentional deletions, fire, flood, theft, etc. can all cause catastrophic data loss. Have a look at this post: http://www.readynas.com/?p=3153
You would be much better served to leave the Duo in X-RAID mode and get an external USB drive to make your backups.
