Thanks for the input! Is there anything specific that I should do to improve the configuration? Or anything to steer clear of? Also -- would I be able to fix/rebuild with the same disk that has the issue, assuming it wasn't because the drive died?

The ability to add disks of various sizes is what drew me to unraid. However, the majority of the drives I have laying around are SSDs that are all different sizes. I've since learned that SSDs in the array could cause issues with parity because of TRIM/discard, etc. That said, I would like to know if adding a few various sized SSDs to my array would cause long term issues if the parity drive is an Ironwolf HDD. Do SSDs cause issues when just set as the parity drive? Or do they cause issues if there is a parity drive combined with any amount of SSDs? I mostly want to make use of array protection, without having to go out and buy a whole bunch of new drives. But I don't think i fully understand the underlying issue. Please help guide me!! I've setup a server on 6.12.9, and am not sure what the most up to date advice is. Desired Array Setup: Parity: 4TB Ironwolf HDD Disk1: 4TB HDD Disk2: 4TB HDD Disk3: 2TB SSD Disk4: 1TB SSD Disk5: 1TB SSD Disk6: 512 GB SSD Disk 7: 512 GB SSD Disk 8: 120GB SSD Cache VM: 1TB NVME App Data / Docker: 1TB SSD Write: 1TB SSD
