Seq is the same, while 4K tests are almost the half, why?
Where was that from?  What was the review system?  AMD systems sometimes have less performance with SSDs.

12k iops thats normal, latency is ok, temperature a little bit higher, at 75° it will throttle
max bandwith (read/write) from your first picure is also ok (pcie x4 gen3)

anything in between is mostly windows related (cache/drivers)

Just for comparison.. https://www.newegg.com/Product/Product.aspx?item=N82E16820147689 

If you look at Read/Write performance, your speeds are right on.  In fact, your read is slightly faster.

Hello everybody,
this is my configuration

Fatal1ty AB350 Gaming-ITX/ac
Ryzen 1700
Corsair 16GB Ram
Sapphire RX480

Today I received the new NVMe M2 Samsung 970 EVO 250GB. Connected it to the Ultra M.2 port on the bottom side of the motherboard.

I updated to 4.60 BIOS and installed Samsung drivers, but I get these results:



Aren't them low compared to reference test?

They're almost the half...
