X-Raid vertical expansion - harddrive compatibility
We run a ReadyNAS 4200 - RN12T1210 (RAIDiator-x86-4.2.31) with 12 of 1TB harddrives drives and we want to proceed with a vertical expansion. Unfortunately the harddrive compatiblility list is listin...

You are saying that I won’t be able to get more than 16 TB per volume. Can I assume that it is not worth it to replace all 1TB 12 harddrives with 2 TB since the system will not recognize more than 16 TB?
You could do a factory reset with 12x2TB in place. That will work, and give you the full volume (22 TB with RAID-5, 20 TB with RAID-6). You won't be able to expand that volume, and since it requires a factory reset, you would need to restore all the data from a backup.

However, if I can get an extra 7 TB to the existing 9 TB that will be ok for a few more years and the next upgrade will be the unit itself.
That is not guaranteed, it depends on the initial size of your volume. For instance, if you started with 1 TB and then added the remaining disks, then you'd already be at the growth limit of your volume. You'd have to look through the expansion history to figure out where your ceiling is.
Thanks meshed but yours is a more advanced unit and I don't think 4200 is accepting harddrives larger than 2TB (at least not acordingly with compatibility list).

The 4200 v1 has a 2 TB drive limit for bays 5-12, but bays 1-4 will accept larger drives. The 4200 v2 accepts the larger drives in any slot.
The HCL for legacy NAS hasn't been updated for years, so it is not a useful guide. I suggest enterprise-class drives for this unit (since you do want good handling of vibration). WDC Red Pro or Gold would work well, as would the seagate equivalents.
There are two expansion limits with XRAID on OS 4.2 systems
- a volume cannot expand over 16 TiB in total size.
- a volume cannot expand more than 8 TiB from its starting size.
Is the 4200 v1 able to upgrade to OS 6?
If so this may offer more flexible options
The hard drive size limitation on the 4200V1 is a motherboard issue, not an OS one. You can update the 4200V1 to OS 6, and there are a lot of good reasons to do that, but handling larger drives is not one of them.

It's true the OS6 won't help with the 2 TB limit on bays 5-12 (which as Sandshark says is hardware), but it will remove the two limitations I mentioned above.
