ReadyNAS 516 / OS6 dual redundancy with X-RAID2
Hi, I've been looking into this and been unable to find a definitive answer... If I were to setup a new ReadyNAS 516 with 4 freshly installed disks, would I be able to configure X-RAID2 in dual r...

With OS4, converting to flexraid required a factory reset. That's not the case with OS 6.
If you are starting fresh, then you start with 3 disks, change to flexraid and add the fourth for redundancy, then switch back. It isn't intuitive, but isn't difficult either.
Alternatively, you can insert all four, switch to flexraid while the volume is building/syncing. You can then destroy it (while it is building) and recreate it as RAID-6.
So it's not easy and intuitive like is was on OS 4.2
To summarise, when loading or factory defaulting a new system with 4 disks, one should convert to flex-raid level 6 and then revert back to XRAID-2 to benefit from dual redundancy over the 4 disks.
Thanks...

Yes.
I've got ya... However, is there any reason to even both going back to X-RAID2. I mean RAID 6 would give the dual redundancy.

I agree that you don't need to switch back - if you see a reason later on, you can always switch then.
Dual Redundancy in XRAID-2 is also RAID-6 of course, since XRAID-2 is built on top of standard RAID.
