RN 316 Installing extra Drives 8TB
I currently have 2 x 8TB Ironwolfs installed in RN 316 as X-Raid (Raid 1), mainly used for storage of movies and photos.
I have just purchased another 2 x 8TB Ironwolfs to install, do we need to turn off the NAS to install the drives or can install on the fly?
What is the best raid option? Raid 5 or raid 10? what are other users doing at the moment?
Thanks in advance

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.

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.
