Question New SSD performance

[dedeki]

I've bought a SAMSUNG 860 EVO 500GB SSD and I made a clean installation of Windows 10.
It seems to me that the benchmark results are below normal. What do you think? In particular Random Read 4KiB (Q= 32,T= 1) e Random Write 4KiB (Q= 32,T= 1) are low.

But overall , very good results.

I'm disappointed because the SSD I had before was a Micron 256GB, a 5-yaers-old model, but has this very good performance:

Do you think the SSD is faulty or not?

Normal results. Don't see anything to worry about.

Q32 results are not that important. You most likely will not have any Q32 workload.

Do you think Spectre patch could influence the result of the test on the new SSD?

 

[SkyNetRising]

Possible, I guess.

None -all above is true.
