Question Crucial 2TB NVMe SSD acts strange or not?

[apalace]

I got a new "Crucial P3 2TB M.2 PCIe Gen3 NVMe Interne SSD, up to 3500MB/s - CT2000P3SSD801 (Acronis Edition)" And I am kinda skeptik about it.
I unrared a big folder (113 gb) and was unrarring but every few minutes it hangs for 5 sec then continues. I took a screenshot of the performance, you can see the diagram goes up and down while unrarring

Is this behavior normal? Or something is wrong with it and I better return/exchange it?

And here a Read/Write performance test, the Read shows a bit slower than it is supposed to be (advertised as 3500 MB/s):

Any help/ comment please?

Sounds like the SSD cache is filling and catching up. Yes, this can be normal with some SSDs.

BTW, here is a review from the site:

Thank you for your answer.
Does it cause any speed issue when running programs or games on it because of this behavior?

Not really. Take a quick read of the review. That is a decent SSD. You are seeing behavior based on the task being performed. During normal use, it would be transparent to you.

When I started reading the review, it led me to Crucial site, where I found software programs to download for optimizing/updating the NVMe.
One of them called "Crucial Storage Executive", where they suggested to download, then performed a firmware-update if found. And what blew me away is an option in this program, is called "Momentum Cache" where they claimed if enabled will make the drive 10x faster.

So I did a firmware-update at first, then enabled the "Momentum Cache", restarted my PC. I performed a Read/Write test after that, and how in the world is this possible ? :

Is it safe or what? On their page they recommended it, but what a speed?

Should be safe. Rather impressive numbers.
