SSD speed really slow + odd (read + write speeds identical at 30 MB/s)

I recently noticed that the SSD (a Micron M.2 Sata SSD) in my Acer Laptop seemed to perform quite poorly (copying to a USB drive was faster than copying from and to the SSD).

So I ran multiple benchmarks (CrystalDiskMark, ATTO, AS SSD), all giving similarly odd results:
sequential read and write speeds are almost identical AND seem to somehow be capped at a mere 30 MB/s.

Even I can see that this is absolutely not SSD-like performance / worse than HDD.

What might cause these results and, more importantly, how can I resolve this / get back the speediness I'm used to?

I'm happy to give any requested debug / hw information if needed.

how full is the drive?

how full is the drive?

178 out of 237 GB of drive C are used, so about 75% full.

Okay, so I did some more research, and as it turns out, a behavior like this is completely normal and to be expected.
SSD benchmarks just aren't accurate most of the time because of how SSDs work.

This is a pretty good article on the topic: https://www.seagate.com/tech-insights/lies-damn-lies-and-ssd-benchmark-master-ti/

Turns out confirmation bias has struck me and my SSD seemingly performs just like it should. Phew

I don't think that's normal my Samsung 970 m.2 is around 450 gb full without overprovisioning and it still gives me same speeds as it used to give me before when I just bought my ssd... I think there is some problem with ur ssd might get it checked from a service centre??
