I've installed a new Western Digital 4TB NVMe SSD in my PC, but I'm only getting 90Mbps speeds. By contrast, my older Sabrent 2TB SSD reaches the full 1Gbps speed. Both drives are in the same system, and the new SSD has Windows 10 installed. I even tried testing in safe mode and even reinstalled the OS, but the speed issue persists. Does anyone have any ideas on what could be causing this problem?

What exactly are you testing your speeds on? Is this for internet connectivity, or something else?
Make sure you're using a Gigabit Ethernet cable. If it’s not at least Cat5e or Cat6, it might be holding back your speeds. Just a thought!
That makes sense! I'll double-check the cable I'm using.

I'm testing internet speed. The original SSD gets 1Gbps, but the new one is stuck at 90Mbps.
