Samsung 970 Evo NVMe M.2 SSD Running Half Speed on ACER E5 475G

Hi, I just recently bought a Samsung 970 Evo NVMe M.2 SSD 250GB, and sticked it to my ACER E5 475G. I have heard bad stuff about cloning your old OS and put them on the new SSD, so I started fresh, I installed everything from scratch. All is well, I can even feel the difference, it is FAST!

Until my curiousness tickles, so I ran the benchmark test.


Benchmark result on the Samsung Magician.


AS SSD Result

As you can see, the result showed the Sequential speed is not even half the advertised speed for 970 Evo. It should've been Up to 3.500 MB/s (Read) and 2.500 MB/s (Write). 
I did try to update all drivers to the latest, I even update my BIOS, but no avail.
After did some digging, apparently the Samsung 970 Evo needs to be on PCIe 3 x4 interface. 


Samsung Magician showed my SSD running on PCIe 3 x2. 


HWiNFO64 says my PCIE can go to Maximum Link Width to 4x, but my current Link wodth is stuck at 2x.
The question is, what can I do to make my Samsung 970 Evo run on its max speed as advertised?

Thank you.

    Hi,
    You can not do anything to make it run at full speed, most of the laptops are restricted to 2 lanes for PCIe in BIOS, 4Lanes are enabled only for Desktops and few laptops. 2Lanes restriction is essential for the SSD to work efficiently with the rest of the hardware in your laptop.

    From my limited experience in cloning HDDs to SSDs, there are two factors in cloning. First is the SSD is usually smaller than the HDD. So you need to be sure the SSD is big enough. If it isn't you need to move some of the data files from the HDD to an external.

    The second factor is you need to ensure Windows is fully updated. If you clone with updates ready to install you can run into major issues. For another computer, this was a major problem. Now before cloning, I make sure Windows is fully updated and I temporarily shut down automatic updates until the clone is successful.

    As for the speed that's still very fast. I have a different model and I got a Corsair NVME M.2. The Sequential speed runs at around 1450 mb/s. 

    I have an older Toshiba laptop running a SATA SSD where the Sequential speed runs between 400 to 500. Between my Acer and older Toshiba, I don't see any difference with Windows. With Photoshop my Acer is a little faster but not very noticeable.

    I'm not a gamer so the speed between 1204 and 3500 may be more noticeable. 

    I am not super technical but what I learned is the biggest bottleneck for most laptops today is the hard drive which you did a great job upgrading. You didn't say how much RAM you have. That may improve things slightly but there are other factors and you will never get to 3500.
