Hi, I just bought a new Kingston USB flash drive and when I tried it I noticed that when copying a file from the laptop to it file transfer speed keeps reducing to zero and freezes then goes back to the normal transfer speed and I tried it on a different laptop and I had the same issue. I searched for a fix to the problem but I came empty-handed and I need to know if the problem is in the flash drive or not so I can return it
The USB is 3.0 and I am connecting it to a 3.0 USB port. I made it on better performance from device manager
I also full formatted the USB and changed its file system but nothing changed the problem remains the same
An image shows the transfer, and when copying large files it makes the transfer take longer time than it should take

There are spike on the picture once in 5 seconds. As for me this is not normal.
But may be this is normal for this model if it has input cache - fill it in a second and then write this data to main storage during 5 second interval.
High disk queue level speaks for this suggestion.
I recommend to ask clarification from Kingston support.
I have been having the exact same problem only my transfer speeds drop from 80 mbps to 5 kbps in less than 2 seconds and then, it sometimes drops to 0. It will stay at 0 for a minute or two, then fly back up to maybe 35 mbps and then down it comes to 0 again in about 2 seconds. I am trying to transfer a 95 gigabyte file from one of my SSD's to a brand new Adata 128 gig thumb drive. I have tried 4 different thumb drives all with different capacities and I get the same thing. This never used to happen on my computer until about 3-4 months ago after a win 10 update. That update also messed up a few other things on my computer which I had to fix. (It made my back up SSD no longer show up so I could not back up to it until I fixed the windows issue) These Adata drives are pretty fast and a file like this would usually only take maybe 5 minutes or less but now, I can let it run for 4 hours and it shows "Transfer 2% complete". I have spent the last 4 hours on Google reading and trying ALL of the "fixes" recommended by M.S. and other users. (When one did not work, I re-set the setting back and tried another one and so on.) In my research I have seen hundreds of posts by folks describing EXACTLY what is happening over here and they all were using different computers and different thumb drives, yet we all get the same result. Does anyone at Microsoft know how to fix this please???? If I knew which update messed up my usb3.0 I might try rolling it back (if it would let me) but I have no idea what part of the update messed it up.
I don't think it has something to do with Kingston. I have the same problem with all of my harddrives including 1 Kingston drive. I exactly get the same graphs as the OP.
When i used these drives on a laptop of my colleague, it uses the full speed.
When I built this computer, I put in USB 3.0 to take advantage of the high and fast transfer speeds. somehow, windows 10 is stopping this from happening. I tried all of the earlier mentioned suggestions from M.S. and the results are exactly the same with many different thumb drives and SD cards. However, I can take those same drives and plug them into my old windows 8 computer (USB 2.0) and the transfer rates are about 100 times faster than on windows 10 with USB 3.0. and they never slow down or go down to 0. There must be something going on here and M.S. needs to fix this or tell us how to work around it. All was fine until a windows update a few months back.
same problem here. windows 10 PC. no problem on other windows using same usb disk. have not found any solution since last year, this is such a pain on a very expensive windows 10 license?
