After performing a few clean install I continue to experience poor read

Open I will have to wait approximately 45 to 90 seconds before Nautilus
launch so that I can select the file. The same goes for any application

the window after I replaced BTRFS with XFS, the only noticeable
difference is with XFS it takes a few hours before I experience the
same behaviour with slightly shorter delays for Nautilus opens.

Something is seriously wrong with that machine!  I also use Fedora 33 with 32G RAM but with a single Kingston SSD on BTRFS, with an old gen-2 i7 processor as my main desktop.  Its very fast, booting in 5sec, and apps come up in <1/2sec.

Assuming that your logs are clean and you're not showing disk or memory errors or have rediculously-high CPU utilization, I would suspect the RAID controller is either misconfigured or broken. Is the RAID battery ok?
