    Slow SD card reader after latest Win10 Creators Update (May 2017)


    My computer recently did the "Creators Update" and my USB 3.0 SD card reader speed dropped to about 1/3 of what it was before the update. Before the update I could transfer video/photo at a rate of about 90 MB/s but now the maximum with the same cards and content is about 30 MB/s. Both read and write speeds were affected.

    My external hard drives (also connected via USB 3.0) were not affected. Their read/write speeds remained the same.

    Has anyone found a fix for this problem?

    Thanks in advance,

    What is the Make and Model# of your Computer/Motherboard?
    go to the Manufacturers Support/Download Drivers, type in your Make and Model# or Service Tag#, choose your version of 10 (ie) 32bit or 64bit. Download the SMBus Controller or Card Bus driver for your model.
