I want to upgrade my file server but I'm not sure how to get there with ports/drives etc. I know I can upgrade the pool size by replacing drives one by one but that will not get me to the double parity. If I want that I need to create a new pool but only have 6 sata ports to work with.
The file server uses an n100 board and while it has a pcie slot I understand it to be very slow. Is the best plan to get a pcie sata card for building the new array then move that to the motherboard ports once finished?
Ancillary question is do I really need double parity? This is for a media server and I could conceivably reaquire all the media but it would be a large investment in time and bandwidth. Currently I have 11tb of media and am going to try and upgrade the quality of much of what is saved.
