Preserve assignments is just to facilitate when using the same devices, since you'll not be using any of the existing array devices no point in preserving them, you can still preserve cache (or don't and just re-assign them).
Don't know what you mean by this, drives don't auto mount, they are just detected, also preclear is optional.
Like mentioned, preclear is optimal, drives can be assigned to the array at any time.
New config is done BEFORE adding new drives.

Windows isn't case sensitive, so it will show only one of them.
Get one of the recommeded LSI HBAs, any LSI with a SAS2008/2308/3008/3408 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, 9400-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed.
Unraid it's running out of RAM, and there's very little available, I don't know what this is but it's using a lot of CPU:

If you don't know which app is it boot in safe mode with all dockers disable them start enabling one by one.
While the controller is bottlenecking a little it's not the issue, please post diags during a parity check, make sure no other array activity is going on, there were some small writes to the array in the previous diags.
