Issue with USB 3.0 Transfer speed (Locked at around 25Mb/s)

HP Recommended
HP Compaq Elite 8300 AiO
Microsoft Windows 10 (64-bit)

Hello everybody,


I have a strange issue with USB3 on this computer only: when I copy files to my USB3 flash disk transfer speed locks at around 25Mb/s.


I am using the fastest USB3 flash disk available "Sandisk Extreme USB3 64GB"

Even when I use the fastest USB2 flash disk "ADATA Professional Series PD7 Turbo Speed USB 2.0 flash disk" it locks around 18MB/s.


  • Tests done copying 1 file around 5/10Gb
  • There are no updated drivers.
  • There are no USB2 devices pluged on the computer
  • Tests done on all USB3 ports of the computer
  • Flash disks working at max speed on other devices

This happens only on this computer, my flash disks always work at max speed on my other computers/tablets/macs and I haven't found a solution up to now for this computer.


Thank you in advance for your help.
