Question SSD Write speed very slow

[C1rm0ska]

Hi!
My SSD's Write speed is kinda slow and the average response time is insanely high.

340 GB free of 475 GB

This usually happens when I go below 260 GB free storage, but this is happening now always

What specific model is your Samsung SSD?

 

[helper800]

What is your full system's specifications? Most important would be motherboard, and SSD model.

 

[USAFRet]

And after your hardware specs, we're going to need screencaps from CrystalDiskMark and Samsung Magician Performance test.

It's Samsung PM991. An OEM drive.

Was seeking clarification since the original picture was cropped.

There was a thread posted a couple months ago regarding a Samsung SSD doing something similar. Performance was tied to cache limitations. That rung a bell when I saw the picture posted here.

My questions would be the age of the drive and system it is in (most likely a laptop). Also, strange to see the SSD to be utilized fully. Unless the pic is made from benchmark software that did utilize the drive fully (but looks like Task Manager to me).

As USAFRet said, i'd also like to see what Samsung Magician says about that drive. Also, CrystalDiskInfo for power on hours and TBW is nice to look at.

Yes, it was Task Manager and I was doing a Samsung Magician Benchmark, but when I download games, this happens very often.

The age of the drive is almost 3 years/around 3 years

Which informations should I send from Samsung Magician? S.M.A.R.T informations?

 

[USAFRet]

but when I download games, this happens very often.

That is irrelevant for the drive speed.

Screencaps of CrystalDiskMark, and the Performance result from Magician.

Note:
Write speed should be 1.2 GB/s, I have tested it months ago

 

[USAFRet]

Right.
That write speed is very very slow.

Once more time...CrystalDiskMark, (not -Info)

 

[C1rm0ska]

Once more time...CrystalDiskMark, (not -Info)

Yes, sorry.
I just realised it.

 

[COLGeek]

That is low. I wonder if seated properly in the M.2 socket and how Magician is detecting that interface (Drive Details).

[COLGeek]

Which M.2 socket on the motherboard is this in?

 

[USAFRet]

Yes, sorry.
I just realised it.

Oh, thats bad.

 

[C1rm0ska]

Which M.2 socket on the motherboard is this in?

There you go:

Sorry, I don't know the name of it, but I guess that would be enough ↑

 

[COLGeek]

When you installed in that socket, did you remove the plastic film that covers the thermal pad often used with those heatsinks that covers the SSD?

 

[Aeacus]

Another option could be trying to put the drive into 2nd M.2 slot. Since it could be the issue with 1st (upper) M.2 slot on MoBo.

Testing this wouldn't hurt anything, but at least would narrow down if the issue is with MoBo or the drive itself. But there is an serious issue, since your drive writes are quarter of what it should be (250 MB/s vs 1000 MB/s).

Now, that is a very good question
I probably didn't

I will test the other one then

That would prevent from cooling properly. Moving to the other socket, as previously suggested would be good to compare results with.

I will do that later

I removed that plastic film, the performance got a bit better
