RN516 Expansion to 24TB?
I'm rapidly running out of storage space on my RN516, running OS 6.10.4. I have about 1.64TB free of a total of 18.17TB of available space. I'm running RAID 5 on 6 4TB hard drives. I use this NAS to store my movie collection which feeds a separate PLEX server.
Files are backed up, via RSync Server, to a ReadyNAS Pro 6350 running OS 6.10.4, with 6 4B drives for a total volume of 18.16TB. This NAS is also running out of space quickly.
My question is this: What is the most economical way of expanding the total volume on both of these NAS's? If I start with the RN516 first, replace all 6 drives with 6TB drives, and "factory reset" the NAS, will I get to about 24TB in total volume? There used to be a calculator of sorts on the Netgear site at one time but I cannot find it.
Before expanding the RN516, I plan to 'clean up' the 6350 first as it contains old files that were backed up. I will 'factory reset' the 6350 and a clean, empty 18TB volume. Then, the RN516 will complete a full RSync backup, creating an identical copy of the RN516 on the 6350.
Once the RN516 is expanded with the bigger drives, I plan to 'back up' the files from the 6350 back to the RN516. Once completed and verified, I start the disk expansion process with the 6350, assuming I can expand it beyond 18TB.
So everything hinges on the ability to expand the volumes past 18TB. Can I do this on both the RN516 and 6350?
Thanks for the valuable tips on Snapshots. I will make sure all 4 NAS's are setup this way. I've schedule in Scrubbing, Defragmentation, and Balancing to run every 4 months, after an initial run in January!

- Since you are running OS6 you can expand past 16TB and by more than 8TB. Those limitations of RAIDiator-x86 4.2.x do not apply.
If you are using X-RAID replacing two disks (one at a time, wait for resync to complete etc.) with higher capacity disks would be sufficient to get some vertical expansion.
Having said that there are advantages from creating a fresh volume with all the higher capacity disks in place.Yes, I'm using X-RAID with the 6 4TB drives in Raid-5.
Is there a calculator or formula that I can use to determine the most economical path to expanding the volume?
If I'm replacing 2 drives in the NAS (one at a time, as you suggest), what is the impact of using a 6 TB vs 12TB
or even 16TB drives? Trying to do some cost/benefit analysis on getting the most space.
