How to downgrade RAID1 to JBOD

If you are comfortable with ssh, there is a thread here that gives you information you need to undo the RAID-1: https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Reducing-RAID-size-removing-drives-WITHOUT-DATA-LOSS-is-possible/td-p/1736125
You can also do a factory reset (either via the boot menu, or from the system->settings->update page). Remove the new disk before you do that. Then convert to flexraid before you hot-insert the new disk.
I suggest unformatting (or zeroing) the new disk in a Windows PC before you hot-insert it.
