Best practice is to make sure you have a backup before manipulating disks. (FWIW, RAID is not enough to protect your data, so you should have a backup plan in place anyway).
The precise steps depend on whether you are wanting to expand capacity, or whether you are wanting to create RAID-1 redundancy. So please post back with your intent.
Personally I always test new disks in a Windows PC before installing them in the NAS. I'd rather detect out-of-the-box failures before I install them. I start with a full non-destructive test, followed by a full write-zeros test. I have had some drives pass one of these tests, but fail the other.
Toshiba allegedly has a diagnostic utility, but I am not seeing how to download it. Seatools might work, or you could try some other test tool.
We do not want to enable Raid1. We just want to add one more 8TB to increase storage space

Then first make sure you have enabled FlexRAID. If the X-RAID control on the volume page has a green stripe, then click on it to disable X-RAID.
Then hot-insert the new disk (ideally blank). You can then use the volume settings wheel to either
- create a new volume, or
- concatenate the new disk to your existing volume.
The second option has a significant disadvantage - when either disk fails in the future, you will lose all your data. If you take the first option, then a future failure would only lose the data on the failed disk.
If you do take option 1 (as I am recommending), you then can move some shares to the new volume to balance the free space. The built-in backup jobs are useful for this - you
- create a share with a temporary name on the new volume
- use the backup job to copy one of the existing shares
- delete the existing share
- rename the new one to match the original
Normal users will just see the list of shares (not the volumes they are on). Only the admin user can navigate the volumes.
