Slow transfer speed from HDD to USB 3.0

[Omer27]

I am using HP Omen 15 dc1054nr with Windows 10 64-bit, version 1903.

I noticed that the transfer speed from my HDD into a USB 3.0 is slow, like 34 MB/s at max. It starts off with 150 MB/s for a few seconds and then decreases to 30's. Copying from HDD to the same HDD starts off with 1.2 GB/s, and falls down to 40 MB/s at max. Can someone please help me in resolving this issue. The copying speed is like this since I got the laptop.HDD to HDDHDD to HDDHDD to USB 3.0HDD to USB 3.0HDD to USB 3.0

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help,  I have a few troubleshooting steps we could try to fix the issue:  

Firstly, Update BIOS: https://support.hp.com/in-en/document/c00042629

Next step Turn off Auto-tuning:

1. Press Windows key + X and select Command Prompt(Admin).
2. Type “netsh int tcp set global autotuninglevel=disabled” and press Enter.
3. Now try to transfer the files and check the data transfer speed.
4. Again go to Command Prompt(Admin) and type “netsh int tcp set global autotuninglevel=normal” and press Enter.
5. This will turn on the Autotuning again.

Hope this helps! Keep me posted for further assistance.

I did both. Updated the BIOS, as well as the other thing, although I used Powershell(Admin). Still same problem, started copying at 2 GB/s and in a couple of seconds went down to 40s MB/s

Thank you for posting back. 

As you've performed relevant troubleshooting steps and the issue persists, I would recommend reinstalling Windows Operating system will fix the issue. 
 

The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.
