    Lenovo 14W eMMC SSD Slow, ReadyBoost disabled, no pagefile.sys on USB.


    Hello All,

    I had currently bought a Lenovo 14W for my son but I am underwhelmed with the performance of this PC. The CPU is always at 100%, the Disk access is always at 100% and if the RAM is 100% filled, the paging file runs extremely slow.

    The system has 4gb eMMC drive and 4gb RAM embedded onboard.

    I have purchased a Lexar USB3.1 Jumpdrive S47 64gb to assist to increase the performance as this system is not expandable.

    Lexar USB Flash Drive 64GB
    75 User benchmarks, average bench 38%
    60GB free, PID 0cd1, Lexar Jumpdrive S47 USB 3.1 Low-Profile
    Operating at USB 3.2 Speed
    SusWrite @10s intervals: 42 43 43 43 43 43 MB/s
    Performing above expectations (83rd percentile)
    74.1%
    Very good
    Read 226
    Write 34.5
    Mixed 80.7
    SusWrite 42.9
    101% 96 MB/s
    4K Read 12
    4K Write 9.5
    4K Mixed 10.4
    721% 10.6 MB/s
    DQ Read 17.4
    DQ Write 17
    DQ Mixed 12.6
    1,071% 15.7 MB/s


    The USB thumb drive is extremely fast and is actually faster than the eMMC drive by 2.4 times.

    In Windows 10 build 1909, I tried to modify the Virtual Drives on the system properties to add the paging file onto the USB drive. The USB drive does not show up at all. I then tried Readyboost to enable it on the drive but then I get the error: This device cannot be used for ReadyBoost. ReadyBoost is not enabled on this computer because the system disk is fast enough that ReadyBoost is unlikely to provide additional benefit.

    Now this is BS as I have tried another caching program called eBoostr and it is not really the same but it did increase the performance of Windows 10. The system was peppier, performed faster and the CPU and Disk 0 was under 95% usage.

    My goal is the following:

    Find a way via the registry to allow USB Thumb drives to be allowed to be used for pagefile.sys
    If the above fails, find a manual method to force enable ReadyBoost, Allow USB thumb drives to be enabled by force and see if it will provide a much needed performance boost. I have tried the current fixes for this however, since ReadyBoost is disabled by default due to SSD, no drives are listed in the registry for ReadyBoost.

    Currently, the system must not reach its 3.8gb RAM limit otherwise the paging file becomes horrendous to the CPU, Disk and RAM performance..

    Ideally, I would like to know if it is possible to "Build" my own Registry settings to enable the USB Thumb Drive Pagefile.sys

    Thanks in advance for all that can assist with this.

    For the time being. It will become progressively slower. UFDs are not build to work in the way you intend. An external SSD would be much better.

    That USB thumb drive is not that fast, only about twice the speed of average cheap basic ones that I have from quite a number of reputable manufacturers.
    Pretty sure it would not be much use as a Page file because of the USB interface.

    It's impossible for WIndows 10 to be installed on a 4GB drive. The last Windows that would run on a 4GB drive was Windows XP.

    Was a Typo... 64GB eMMC.

    64GB is plenty to run Windows 10. Have you thought about doing a clean install?

    I would love a SSD external but
    • computer is for my young son
    • he moves around a lot.
    • Don't want something big off the USB port to break.
    • Low-Profile is a must.

    I have ran Win7 systems via USB. Not fast but definitely faster than this Lenovo Laptop...
    the eMMC paired with the slow RAM on this system is killing the machine. I have ran performance tests on both the eMMC and the USB and the USB is actually faster.

    There was also a model with a PCIE Slot to allow to add NVME Card to it. While I searched the Internet, I found others tried to upgrade my model 14W but the PCIe Interface was missing. I would like to try to install one but not sure if it would work or require any additional surface mounted caps.

    Either way, for those looking at PCs with eMMC, don't buy them. You are severely limited with the system and will just be a headache with all those delays to run multiple software. eMMC and onboard RAM is best for Android/iOS, not Windows 10. Too much reliance on pagefile.sys to keep system running smoothly.
