Slow SSD random read speed?

Question

Solid State Drives

Bought a new SSD Samsung 970 evo plus. There are no problems with sequential speed, while random speed is half that of other people. What could be the problem? Motherboard ASRock B365 pro 4, stands in the first M2 slot. On the first picture - my test, on the second - people from the market (there are many of them).

Answer 1

Pretty normal speed.
And given how you measured it, it's not speed, but the weather in Africa.
How can you measure the speed of a disk if there is a system on this disk?
