Copy speed very slow in windows 10

Using NAS Network mirror drive SATA to NEW USB3 thumb drive.

If downloading from the 120 MB Internet to the NAS, speed is constant.

PC SATA to NAS, speed is high.

The USB 3 starts out high, then drops off.

Windows 10 Slow Deleting or Moving Files? Here’s the Real Fix

 

Windows 10 Network speed drop off when copying files

This is a constant problem.

when copying files from ComputerA to ComputerB, both on the same network, the speed starts off at 10mb, which is nice and fast, then about 30 seconds in it drops off to 150-900k and stays there.

why does this happen?





A few things I have tried:

1. I made sure nothing else is using my network, no internet activity, no devices, ect...
2. I made sure both computers on the network are properly networked with permissions and accounts.
3. My router is blazing fast, my internet speeds are 1gbps
4. Tried testing both TO and FROM computer A and B
5. I have no "low power" settings on either computer, both are using maximum performance in every setting including advanced settings
6. Neither computer is 'asleep', the HD and the system are both fully live and active

The problem is not intermittent, it is constant - at about 30-45 seconds the speed always drops off.

Any ideas?

 

DL speed drop

Hi,BenjaminMello

My name is Erik. I'm an Independent Advisor and I'll be glad to help you today.

How many devices that are connected to the internet, possible that you been experience a high traffic connection to your internet,that's why the speed drop while you were downloading and if only one device is connected, I suggest to run a speed test, make sure
to get the download speed and then the Upload speed, if the Upload speed getting only 1mbps and then you have an issue to your connection, and I suggest to contact your service provider and to trace your line connection and asked what is the upload standard
upload speed that you have in the package of your internet, because if your getting a 40 Mbps of speed expect the upload speed should be more than 5 Mbps to 10 mbps.that will depend what packaged that
