Gettin super Low speeds at USB 3.0 (27 MBps max)!!

[gam0reily]

Hello,

Sorry if it isn't the right forum.

But I am having trouble transferring my files via USB 3.0 from my External drive, a seagate GoFlex 500GB to my laptop, an HP Pavilion g6-2005AX.

I am new to USB 3.0, since I got this lappy today itself. So, I did a normal copy-paste to my laptop's hard disk, and the speeds were dismal.

I am averaging out at 22 MBps, with the max going upto 27MBps only!!

please help! What is that have I missed? ANy driver? I am at a dead end ryt now.

Thx in advance

One posting is enough (not 3). Is your GoFlex a USB 3.0 or USB 2.0 device? Assuming the HDD supports USB 3.0, are you connected to an actual USB 3.0 port with the appropriate USB 3.0 cable?

If the answer to any of these is "NO" or your HDD is only USB 2.0 compatible, then you will only get the speeds you are seeing.

My HDD is USB 3.0 enabled, and connected to a usb 3 port on my laptop.
And the cable is the same that they supplied me with.

What specific model of GoFlex HDD do you have?

BTW, got this from the Seagate website:

Q: What does upgradable mean? Can I increase the capacity of my drive?
A: While it is not possible to increase the capacity of your GoFlex drive, the unique and seamless GoFlex cable system transforms the GoFlex, GoFlex Pro, and GoFlex Slim ultra-portable drives into truly upgradable solutions in that you can access the content on your drive with any interface you would like, all by simply selecting the cable that matches your interface of choice. Each drive kit (excluding the drive-only box) comes standard with a USB 2.0 cable for out-of-the-box USB 2.0 performance. However, by simply changing the cable, you can upgrade the speed and performance of your interface to have faster FireWire 800, eSATA, or USB 3.0 transfer rates than that of the standard USB 2.0 drive

This means that many GoFlex devices ship with a USB 2.0 cable. Any USB 2.0 device, including the cable, in the device chain will cause the entre chain to work at 2.0 seeds.

Great research. I think a link to USB 2.0 vs. USB 3.0 connectors would help, so OP can tell what kind of cable he is using. I'll look...

For the B connector, which is probably what attaches to your external device, the difference is easy to see. There's a picture here: http://www.legitreviews.com/article/1150/1/

For the A connector, I'm having trouble finding a side-by-side photo showing the differences. The plastic inside will be blue for most 3.0 cables. I'll keep looking... Try http://www.usb3.com/usb3-info.html

On the same Seagate site, they reference a cable that they offer to meet the USB 3.0 need.

For your USB "head hurting pleasure" this wiki contains tons of info regarding USB:
