Hi all,
I'm getting incredibly slow (5Mb/s) performance from my front and rear USB 3 ports. Transferring single or multiple files to a USB3 8Gb stick is returning these speeds. Nothing else going on at the time.
I have the most recent Etron drivers and the latest (beta) BIOS. Anyone have any suggestions please?
Thanks very much

Hi there,
there may be nothing wrong with the USB ports and it could be down to the make of USB pendrive that you are using. I have a couple of USB3 pendrives and they return different read/write speeds. I have found that my 32Gb stick performs better than my 8Gb one.
-
I'd expect far better than 5Mb/s from a USB 3 drive though - even accounting for different manufacturers!?
What speeds are you getting from your 8 and your 32 - can I ask? Thanks for the reply....
-
Some additional detail - that same USB3 8Gb stick is giving me 6Mb/s over a USB2 port on Win7...
Any other suggestions, anyone? Please? ;D

just transferred a 1.9Gb video file as a test for you.
32Gb stick = 36Mb/s
8GB stick = 15.5Mb/s
-
Thanks, so 3x what I'm getting. Any ideas please?
-
how about intel usb 3.0 port speed?
-
What about Intel USB 3 port speed? I don't understand what your question is.
I've experimented with xHCI settings in the BIOS, tried updating and reinstalling old and new drivers. Nothing seems to help.
Does anyone else have any ideas please?
-
Have you contacted Tech Support? If not, it might be worthwhile doing so as they should be in a better position to offer practical help.
-
Yeah - I did that just now. The automated ticketing system on their main site was down a couple of days ago, so I figured I'd try the forum. I'll post the fix here if one surfaces....

Some more detail - anyone care to comment / validate?
Same USB3 8Gb Stick. One Win7 PC - USB2, One Win8 PC - USB2 and 3 Copying 1Gb mov file
Win7 - USB2 and Win8 USB2
Copy from stick to PC - 35Mb/s
Copy from PC to stick - 6Mb/s
Win8 - USB3
Copy from stick to PC - 55Mb/s
Copy from PC to stick - 5Mb/s - the copy starts fast, but quickly slows
Weird...and still no response from Gigabyte support

I saw this post on another forum. Very interesting.
"The usb 3.0 high bandwidth allows for really fast emptying of the fast disk cache in the initial moment (burst rate), and leave the mechanically slow hard disk platter to transfer small files, requiring constant stop to seek new file. In contrasts, in usb 2.0, the mechanical hard disk also transfer at 15MBps but since bandwidth bottleneck restrict the emptying of the cache in burst at the beginning, the data in the fast cache linger and is transfered at the same time as the platter data to saturate the 30MBps, giving it a more average speed. Now, if you have larger continuous file, like a any file over say 0.3GB. Because there is little seek for small file, hard disk platter will rotate without stopping. usb 3.0 will not be a bottleneck because the interface bandwidth is greater than the hard disk output. On the other hand, usb 2.0 is bottlenecking the mechanical hard disk because of its limited bandwidth. In large file, usb 3.0 will be about 180 to 300% faster than usb 2.0. Find a continuous large file to transfer. I will be surprise if usb 3.0 is slower than usb 2.0."

Hi there,
I just tried a Transcend USB 3 16Gb stick, and got the following results
Copying from stick to PC - 17Mb/s
Copying from PC to stick - 40Mb/s
I guess the headline is "massively variable USB3 performance depending on MFR and file size/type"
Thanks all!
