I almost thought I shot myself in the foot here. I’m using a HP 200g1 motherboard in a NAS (super low idle) and intend to use an HBA in the PCIex1_2 to extend the number of SATA ports from 2 to 4. The 4th port I intend to use if I ever want to run RAID 1, but seeing as how the NAS is being built for a 3-2-1 backup (1 drive active, 1 drive as a daily-weekly backup, and another cloud backup) it is probably unnecessary. I wish my data was important enough for RAID 1. I can’t find any information on this; are some motherboards “limited” to how big the disks can be? HP’s website says it can be up to 1TB but I’m gonna jam two 12TB drives into it.

There’s probably some limit, but it’s never even crossed my mind when building a system. Any modern system should support absurd disk sizes.
Edit: actually since Bay Trail is Atoms and Celerons, you might actually see a lower limit, especially on the Atom. But I doubt 12 TB is too big.
Typically, business-oriented vendors will list the hardware that they’ve thoroughly tested and will warranty for operation with their product. The lack of testing larger disk sizes does not necessarily mean anything larger than 1 TB is locked out or technically infeasible. It just means the vendor won’t offer to help if it doesn’t work.
That said, in the enterprise storage space where disks are densely packed into disk shelves with monstrous SAS or NVMeoF configurations, vendor specific drives are not unheard of. But to possess hardware that even remotely has that possibility kinda means that sort of thing would be readily apparent.
To be clear, the mobo has a built-in HBA which you’re using, or you’re adding a separate HBA over PCIe that you already have? If the latter, I can’t see how the mobo can dictate what the HBA supports. And if it’s in IT mode, then the OS is mostly in control of addressing the drive.
The short answer is: you’ll have to try it and find out. And when you do, let us know what you find!
