December 21, 20223 yr Quick Question. I just want to make sure I understand this correctly. Unraid tracks the drives based on Serial Number and not what Sata Channel they are using correct. If that is correct, I should then be able to take 2 drives in my server and Swap them to different hot swap locations and Unraid would not even skip a beat upon startup? I do not have a raid controller, and there is only 1 parity drive.

Correct. But since you mention hotswap I just want to make sure you don't intend to do this under power. Hotswap not recommended for array or pool disks even if hardware supports it. Even for replacing disks, since Unraid won't do anything with a new disk until you assign it, and you can't make assignment changes with the array started anyway, so no point in hotswap. Be sure to double check connections before startup.

Oh, for sure the computer will be powered down. Thanks for the clarification. I have a drive in the servers Boot drive bay, that is being used in the array since Unraid is booting from a thumbdrive. I currently have 7 4TB disks with one of them being Parity. I am going to install a 16TB disk as the Parity in preparation for future Expansion, but I wanted to make sure that the Parity drive was in the Boot drive slot, as that is not "Hot Swappable" and requires tools and a lot more effort to remove. So I just wanted to be 100% that doing this wasn't going to cause me a headache and a lot of Server downtime.
