Can't get USB 3.0 speed out of my Asus P8P67 Pro mobo

post #1 of 8
Thread Starter 
I just got a USB 3.0 flash drive which is a Transcend 32 Gb Jetflash 760 and StarTech.com 5-Feet SuperSpeed USB 3.0 Extension Cable

I plugged the extension cable to the back of my mobo with the blue USB holes. running a HD bench, I'm not getting nowhere near the speeds that I should be getting (I'm pretty much getting USB 2.0 speeds)

can anyone help me out? not sure if this should be posted here or the HDD forum...

from the device manager, I see that "Renesas Electronic USB 3.0 Host controller" and "Renesas Electronic USB 3.0 Root Hub" are present (twice for 2 ports I assume) so the drivers are in place...

FWIW it's formatted as FAT32 right now

Have you tried plugging it directly and not through the extension? Also did you install the drivers for USB 3.0? without those drives you only have USB 2.0 speeds.

edit: somehow I missed the second part of your post about the drivers being installed already.

Like I mentioned in my original post, I see that they are on the device manager as renesas electronic USB 3.0 Root host controller and root hub

OK, i plugged it in directly to the USB 3.0 port and it went from 35MB/s to 65.67MB/s

still not what I was hoping for (I was expecting over 80 MB/s)

I'm confused why this extension cable isn't working as it should. if you click on the link, you'll see that it was meant for USB 3.0

Your speeds directly connected to the usb 3.0 port seem average, just one example http://www.youtube.com/watch?v=QTTZJncAoTU&feature=related . It would appear your extension cable must be bad.

The advertised specs are probably because they used a non-compressible benchmark such as ATTO Disk Benchmark.

Try that and see if you can get similar results. Also what driver version are you using?
