Question Samsung 970 EVO M.2 Slow Speed

[FrankyS91]

Hi everyone! I just realized that my samsung ssd 970 evo has slow read/write speed despite the official benchmark. It's almost half the guaranteed speed by samsung. I can provide crystak disk mark & info images if needed.

Can you please share your benchmark. If possible with Magician, otherwise crystal disk is also fine.

Does the laptop in question list the specs of the M.2 NVME slot as being PCI-e X4 lanes (32 Gbps?)...

Just wondering if perhaps they only enabled a pair of lanes to allow use with two M.2 slots, etc...; perhaps there might be BIOS options for configuration/prioritizing/enabling X2/X4 lanes, etc...

I really don't know how to see if my motherboard has M.2 slot being pci-e x4, there's just one M.2 slot for what I can remember when I installed the ssd. I checked all the BIOS setup and didn't found any PCI-e setting to switch from x2 to x4. The motherboard model is HP 841C and chipset is Intel Kaby Lake-U + iHDCP 2.2 Premium PCH.

The model you shared refers to a printer!

edit: also as you can se here PCIe my ssd is installed in a M.2 socket with PCIe lane with x4 link width enabled.
