HP Z230 and NVME M.2 SSD adapter

[jacek13700]

Hi. I have HP Z230 with 16GB RAM and I bought WD SN580 NVME SSD with PCI adapter. I connected this  disk via PCIe2 x4, and Windows can see this disk but Bios does not.
But the main problem is speed of this disk. It works like regular SSD disk Up to 390MB/s R/W instead up to 4100MB/s

In device menager no driver errors, but Crystaldiskinfo it shows transfer mode is PCIe 2.0 x1 instead PCIe 4.0 x4.

Also I have GPU that is connected via PCIe2 x 16.

Could someone tell me what to do to speed up this disk ?
thank you

Hi:

Your PC does not have any slots that are PCIe 4.0 x 4 so it would be impossible for your SN580 to run at 4,100 MBPS under any circumstances. 

The only way the SN580 will run near its maximum advertised read/write speeds would be from a PCIe 4 x 4 Slot.

The chart shows the various speeds you can get from the various PCIe generations and lanes:
