ReadyNAS Pro 6 (RAIDiator 4.2.28) Capacity
Hey all - I've seen a couple threads near this question but nothing exact, so I figured I'd ask myself: does anyone know what the final drive capacity is on the ReadyNAS Pro 6? I know it's EOL (or VERY near to it), so I wanted to do my capacity planning earlier than later, and I've seen some threads mentioning 4TB drives, but better to know than to guess. Thanks!
There are two expansion limits with 4.2.28. The first is that a volume cannot expand over 16 TiB. The second is that a volume cannot grow more than 8 TiB from its initial starting point. For both it is the volume size that matters, not the raw disk capacity. The second limit depends on your system's expansion history.
However, you can create larger volumes with 4.2.28 if all the disks are the same size and you do a factory reset with all disks in place. 6x4TB or even 6x6TB should work.
You can also install OS6 on the pro-6 (though you lose support). That has no limits specified for volume size.

Thanks! I think I'm probably outside of support already - I've had it for a while now. I will probably just update to OS6 sooner or later (once I can figure a way to get the data off there).
I assume I wouldn't have the same volume size or size difference issues with 6 that I would with the current OS?

To date, there are no expansion limits identified for OS6.
