Question Samsung 870 QVO 1TB slow write speeds

[troller100]

UPDATE 3: Solved? seems like the 870 QVO sucks and there's nothing you can do about it, the write speeds will be limited to 80MB/s after the cache gets filled.

I was noticing the extracting speed when using WinRAR was very slow, and decided to benchmark my SSD again to see if it's because of that or winrar just being slow, and the write speeds were around 80mb/s on CrystalDiskMark, but Samsung Magician shows 510mb/s for some reason.

When I first installed the ssd it was working as expected, around 500mb/s read and around 500mb/s write, but now it's just slow, without me changing anything.
The drive letter is C: on the ssd and i'm using my windows on it as well.

UPDATE:
After doing 2 more tests with Samsung Magician, it now shows 86/87mb/s write speeds, I really have no idea what is going on.

UPDATE 2:
When starting a CrystalDiskMark benchmark the write speeds will go over 500MB/s(like expected), and then go back to around 80MB/s. This happens once in the start of the video and at 0:39

If someone knows why this is caused and if it has to do something with my slow speeds please let me know!

It looks like the cache is full or it's not using it anymore.

I'm not really experienced in this stuff, and if that's the case, what should I do?

It should clear itself after the system is idle for a bit.
Sort of how it works it writes it to the cache then to the drive to keep the speed up when you run out of cache it writes directly to the drive making it much slower.

So there's nothing wrong with the ssd? And I've never turned on or saw something about "TurboWrite" anywhere since using the ssd, and the performance optimization thing on Samsung Magician is on Standard mode. Only TRIM on.

Wait a while without writing anything to the drive and run the test again.

Fair enough, how much is a while? Is 5 minutes or 30 minutes good enough?

I would think 15 minutes would be fine.
I'm not really sure how long it takes to write the cache to the drive

been around 40-50 minutes since I haven't done any writing, only light browsing(since i have my windows on it)
these are the results, still the same

This may seem a strange question, but when did you last scan this system for malware?

Also, what are the complete specs for this system (make/model of ALL installed components)?

Been a long time since I scanned my pc, I'm careful with what I download/open, and if you're thinking about a malware that is using my SSD, it's currently at 0%.

And as for my specs

GTX 1060 6GB
I5 7400 3.00GHz
16GB 3400MHz
x1 Samsung SSD 870 QVO 1TB
x1 SEAGATE BarraCuda HDD 1TB

Is write cache enabled on this drive?
It should be by default, but please check.

In File Explorer:
Right click on the drive.

Have you tested the performance of your HDD? Does it perform to expectations?

Yes, my HDD is working fine, at least I think these are normal speeds

Yep. Looks okay. Just wanted to see how your SATA performance was with the HDD.

Does Samsung Magician show any available firmware updates for your SSD?

Nope

I'm thinking it might be because of this?

I have my SSD on Disk 1 instead of Disk 0 with my windows also installed on Disk 1, I really don't know if that has anything to do with this, just pointing it out.

Does the Magician diagnostic scan indicate any errors?

When you installed Windows on the SSD, was it the only storage device attached fully (data and power) to the motherboard?

Yes, or I think so, I'm not entirely sure
