    since upgrade win10H2 usb3 transfer speeds cut +75%


    was running win10 2004, then upgraded to H2. Now Macrium Reflect that was pushing over 500megs over my usb3 port is pushing 56megs for backups. . I have gone into the external USB drive and enabled disk write caching with zero speed increased. This is a seagate 5gig expansion external drive, not a usb flash drive

    What gives? just another MSFT screw-up of an upgrade? I can roll back to 2004, I just updated today . 10 days and counting.

    Speed up USB3 File Transfer

    ​I was copying some large Hyper-V vhds to an external ssd from an internal ssd via usb3, and I was getting a sedate 130 MBS even through the ssds can handle close to 500 MB/S and USB3 can handle up to 480 MB/s.

    Of course, we all know that in the real world, you are lucky if you get 50% of that - so 240 MB/s is a reasonable target.

    After googling, I found a truly simple change that sped my transfer up by 50% to 200 MB/s.

    I simply changed the SDD write cache properties as below from device manager.

    Only minor downside is you must eject the drive to safely remove it (should do this anyway).
