When transferring large volume of data, sometime I notice that my USB 3 port seems to go into USB2 mode, and not performing? Restarting the PC fixes it.
I have USB 3 disk and cable connected to the USB 3 ports on my desktop.
How do I know if the USB 3 port has fallen into USB 2 mode? Is there anyway to restart the port without restarting the PC.
Thanks for any helps.
Hello ffrree (keyboard stuck),

Also Crystal Disk Mark app can be used to benchmark drive i/o speeds

I highly recommend Crystal Disk Info app to keep an eye on your drive health and temperature - run it in resident/startup mode so you don't have to remember to run it manually.
I am using Seagate USB3 disk 8TB, but not sure if the buffer is enabled, please advise how ?
How to Enable or Disable Disk Write Caching - MajorGeeks
bottom checkbox should be unchecked in policies tab.
If the Seagate is a mechanical disk it will never be very fast.
A USB 3.0 has a transfer rate of 4800b/s or 600B/s.
A fast HDD 2.5" will never reach 1200b/s or 150B/s
You may see a very fast transfer rate on the beginning. It is the initial where you transfer to a cache memory on the drive. Once the cache is full, you get the slow disk rate.

There is a very useful utility from NirSoft called USBDView that will show you more information for USB devices than you ever thought possible.
