Hello,
I recently bought the NVMe SSD Samsung 960 PRO 512 GB to replace 250 GB SATA SSD from Crucial.
Once everything was up and running I had the impression that it took longer to open programs.
So I switched back to my old SSD and my impression was confirmed.
For example, opening the Windows file explorer is just doubleclick and the window pops up. When opening the file explorer on the
NVME SSD it takes about a whole second to display the window. This goes the same for other programs as well. Even when playing League of Legends the FPS drops below 30 sometimes.
I have installed all the drivers for my motherboard, graphics card, even a driver for the Samsung for the SSD. I updated my bios. My motherboard recognises that it's an NVMe SSD.
I ran the ATTO disk benchmark and got +2GB/s seq write speed and +3GB/s seq read speed.
I do noticed that in Windows taskmanager the latency of the SSD is sometime above hundreds of miliseconds, I saw it once reach about 1400 ms. While I read somewhere on the internet
that the maximum latency should be around 200 microseconds.
I don't know why this SSD is so slow, I don't think that it's normal for that NVMe SSD to be so slow.
I am out of ideas and I hoped you guys here could help me finding what the problem is.
Any help is much appreciated.
Kind regards.
