How to update firmware, help-script, mainsail, etc?

I installed the Creality Helper Script and setup Mainsail about a year and half ago. Since then, I haven't updated its firmware and I see a bunch of things to update in the Update Manager panel in Mainsail.

Is it safe to update everything? Is there any specific order I should follow to update firmware, Mainsail, Moonraker, helper-script?

How to benchmark ZFS?

I'm building a NAS and want to benchmark my pool. It is a 2x2tb HDD in mirror, I have 64 GB DDR4 RAM, and an i3-14100.

I want to check how it performs and compare to ext4, but I'm afraid having this amount of memory will cloud the results.

I'm thinking of allocating a 50GB file in a tmpfs, with random data from /dev/urandom. Would this be enough to trigger I/O to be flushed to disk frequently?

What else can I tune to not have RAM impacting the results too much?

Also, what fun benchmarks to run? I'm thinking of fio, pgbench, copying small/medium/large files. What else would be cool?
