OMEN 15.6 inch Gaming Laptop PC 15-en1000 (2L1F2AV)
Microsoft Windows 10 (64-bit)

I recently bought a Samsung 990 Pro SSD (PCIe 4.0 NVMe M.2) for my laptop (Omen 15 R7 5800H, RTX 3060, 2021), but the sequential read and write speeds do not seem to reach as advertised (7000+ Mbps). Instead, I get ~3500 Mbps. Now, I have tried setting the SSD to performance mode, but the speed remains the same.

So, I'm wondering if the slots provided in my laptop are not compatible with the SSD.

Could someone please help me with this?

Thank you.

Your SSD is working fine.

 

The problem is your notebook's M.2 slot is only PCIe gen 3.0, so a PCIe Gen 4.0 SSD will not run at its maximum advertised read/write speeds.

 

The AMD Ryzen R7 5800H motherboard is PCIe Gen 3.0 as you can see from the specs below:

This chart shows the maximum possible transfer speeds from the various PCIe generations:
