Welcome to the Community!
You can add the disk even if your ReadyNAS is running and since you are on X-RAID the expansion will automatically take place using RAID 5 configuration. Add the disks one at a time until it finishes resyncing and then add the next one.
I would go with RAID 5 personally if you need to optimize the volume cap. You will have to set the NAS to Flex RAID if you plan to use RAID10.

What is the best raid option? Raid 5 or raid 10? what are other users doing at the moment?
I use XRAID (RAID-5) on my own NAS. Though you'll also find some folks using RAID-6 and RAID-10. Both would give you a 16 TB volume (instead of 24 TB).
RAID-6 offers protection against two routine disk failures (instead of the normal one). Write speed will be slower, but I think the bigger concern is that future expansion would require replacing all 4 drives.
RAID-10 offers faster speeds, and protects against some combinations of two disk failures - but not all. You can expand by upgrading two disks (but it can be a bit tricky to identify which two).
No matter what RAID mode you use, you need to have a backup plan in place for your NAS - RAID alone isn't enough to protect your data. It's particular important to have a current backup when you are expanding the volume or replacing the drives.
