Windows 10 - slow working, SanDisk 128GB 3.0 150mb/s

[admin]

I set WIndows 10 on my SanDisk UltraFit 128gb Pendrive (3.0 150mb / s) with WinToUSB.

Unfortunately, somehow everything works slowly, it's impossible to work.

Does anyone have an idea why? Install something? Any drivers? Benchmarks?

In the net I read that with a fast not obsolete USB stick in the USB version should work with sufficient speed for normal use. (my pendrive seems to be okey for something like that)

 

I do not know how to go about it ... any ideas how to start with it?

my laptop is Dell Inspiron 3721

For an operating system boot drive, 4K random read/write speeds are very important. Usually the 4K read/write speeds of common flash drives are always slow, so these drives are not suitable for creating a windows to go drive. 


You said the SanDisk UltraFit 128gb is "speeds up to 150mb/s", but the speed you said is sequential read speeds not 4K read/write speeds, so it may not be suitable for creating portable Windows. 

To ensure that Windows To Go runs smoothly, we recommend that you use an external hard drive, Windows To Go Certified Drive, SanDisk Extreme CZ80 USB 3.0 Flash Drive or SanDisk Extreme PRO CZ88 USB 3.0 Flash Drive to create portable Windows.
