SSD Write speed dropping.

Hello,
I've been having an issue with my PC ever since upgrading to Ryzen a couple of months ago.
The issue is speed of my SSDs, now I don't know where exactly to put this thread because it could be software itself, but after doing a clean install of Windows so many times, I don't even know what it is anymore. Whenever I benchmark my SSD the write speed shoots up to ~300+MB/s which is expected with this Kingston SSD I use. However, after a second or so the speed starts dropping and goes all the way down to 70 MB/s(Read speeds are fine.). I've also started stuttering on games ever since this has started. Funny thing is that it only happens on the SSD that has Windows installed on it(Installed Windows on the other one, then the first one works fine). Any ideas?
Thanks.

The weird thing is that they don't have anything on them besides Windows + both are around 3 months old, and it was the same right after I got them new.(Forgot to mention that one is a Patriot drive)

OK, only 3 months old...my slow Kingston is 6+ years old.

Have you looked at it with the Kingston toolbox application?

Everything seems fine from what I can see, no failures, warnings and overall its healthy. Thanks for the idea, but as I said it only happens when Windows is installed on a specific drive, If I had Windows on my Patriot drive, the kingston one would work just fine.

Then I would put it down to the OS install being faulty.

Since I can tell you're good at this kind of stuff, have you ever had a motherboard cause speed issues? I believe my SSD worked flawlessly on my Intel configuration.

Only if it is connected to a slower SATA port.
But that would be slow all the time.

Both are connected to SATA 6Gbit ports, I think I am going to try changing out the board anyway, thanks for your time.
