USB 3.0 Port Very Slow

Bonesbobman · Aug 19, 2014

Okay so I just got the Asus M5A97 LE R2.0. Whenever I try to transfer lots of data like 1-2 GB, it is very slow. I might get 800KB/s - 3MB/s on average. My case USB has a another USB which you route to the back of the motherboard. Both back and front USB 3.0 are very slow and this has always happened.

The usb file read/write/transfer speed will only be as fast as the usb device you are using itself.
So a usb 2.0 pen drive plugged into a 3.0 port, will only perform as fast as the pen drive itself id capable of performing at, at the 2.0 speed. Also remember, all devices have different quality read/write speeds;

If i used my usb 3.0 pen drive in a 3.0 port, i'd get Read-73MB/s - Write-13MB/s
But plugged in a 2.0 port, it is Read-30MB/s - Write-9.8MB/s

Kingston DataTraveler R3.0 G2

Also, copying a folder of a hundred smaller files totalling 1GB would take far longer than a single item of 1GB, near half the speed

Ohhh. Thanks so much!

No problem

just get usb 3.0 drives in your future purchases to achieve the speeds your motherboard was made for and check reviews of those drives to see what kind of read/write speed they are actually getting too, to know what to expect
