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
