I just bought a 256 gig Vector SSD and a USB 3.0 SATA 6g enclosure. As soon as they come in ill get you guys the stats on just how fast the Intel USB 3.0 controller can move a huge pile of files and one huge archive in Windows 7.

Here's two screen shots 93.7MB/s and 105 MB/s

Clare, you are indeed copying at speeds way greater than USB 2.

Few questions:

1. What model laptop are you using?

2. What model external Hard Drive?

3. Please post a screenshot of your driver properties from device manager.

    Here's how, if you don't know:

    > Press Windows Button + R on your keyboard simultaneously.

    > Type devmgmt.msc , press enter.

    > Expand the "Universal Serial Bus controllers" tree node.

    > Right-click on Intel(R) USB 3.0 eXtensible Host Controller and select Properties.

    > Select the Driver tab.

    > Post a screenshot of this window, please.

Hi Matthys - thanks for your helpful notes Please let me know if there's anything else I can do to help.

1. Dell Inspiron 17R 7720 SE.  NB my hard drive is only a 5400 not 7200 so this will limit my USB 3.0 speed I assume

2. Samsung M3 Portable 1TB drive

3.  Here you are;

At those speeds shouldn't it only take about 10 minutes for 60GB not 20 minutes?  I need to correct my earlier statement. It was 10-12 minutes, not 4-6. Your speeds are definitely not 2.0 though. Looks like you got it working on your system afterall.

Here's another screenshot after all the lenovo drivers update (including chipset driver) and windows updates. I'm copying 11 GB file to my mSATA SSD.

79 MB/s sound about right for my WD Passport which is a 2.5" 5400rpm drive. I'm glad the speed did not drop to USB 2.0 levels. I wonder what happened previously, and why I only got around 30 MB/s. I'm using the exact same installation media, same USB port, can't imagine anything different. Anyone have any clue?

Thinkpad x230t. uefi mode win8pro x64, 8GB ram, crucial msata 128gb.

The 60GB was made up of around 300 albums worth of audio files, in apple lossless format, not sure if that will ave affected the overall duration; the speed varied from over 100 MB/s to around 45MB/s slowest...

That sounds about right for those files.

After installing all the softwares, my USB 3.0 port is still working well. Here are some more screenshots of the performance.

Reading from Adata usb 3.0 flash drive:

Reading from a SSD on usb 3.0 connection:

I think these are good results, and I hope they stay this way.

(tested on thinkpad x230t)

Bruce, what do you show as your internal transfer speeds?  Of course, I am asking about internal hard drive to internal hard drive.  Even when I was testing the Intel Smart Response Technology, my USB 3.0 to USB 3.0 speeds remained at 125 MB/s, while the internal transfer rates dropped to 14 MB/s due to a bad SSD.

It might be noted that David Lessnau and I have the same motherboard (ASUS P8Z77).  His is operating at 2.0 speeds and mine at 3.0 speeds....  If you could find his problem, you might find yours.

Bruce, what do you show as your internal transfer speeds?

I have 2 Force GS SSDs in raid 0 so the speed is a bit more than USB 3.0

Ill be doing the windows 7 test on Monday to see just how fast Intel USB 3.0 can go. I will be transferring test files and folders between this system and a new Vector SSD via USB 3.0 adapter.

Keep in mind that my problem was different than what you guys are talking about now. My problem was that the Windows 8 USB 3.0 drivers are non-functional in the pre-install environment and I solved this by merging the hacked Windows 7 Intel USB 3.0 drivers poster in this thread into boot.wim.

I am doing this test NOT to troubleshoot my own issue (that I solved with the help of the hacked drivers). I am doing this test to help others that feel that their Intel USB 3.0 speed under the Windows 8 generic drivers is lacking.

Once I have some free time ill install Windows 8 and do the same test on the same hardware both with the hacked drivers and again on the generic drivers.

Thanks to everyone contributing to this thread, very helpful information.

Like many, I've been waiting for the Intel USB 3 driver for my Z77 board. My Intel USB 3 speed was slower than the Intel USB 2.

Just installed the hacked drivers and everything is working as it should.

Note for Intel, if any Intel personnel happen to read this thread:

Intel, you should be ashamed of your behavior.

The USB 3 drivers for Windows 8 are easily converted from the Windows 7 drivers, it would be easier if you would get them signed and available for us, your true customers.

Put whatever little spat you are having with Microsoft aside and treat your customers the way that we deserve.

@Bruce Harrison,

Will be interesting to see your USB 3/Windows driver test results.

Whatever happened to Bruce Harrison doing  tests with his new equipment? Are you ok Bruce?

I am also having trouble on Windows 8 USB 3.0 devices. My external HD (Samsung S2 Portable 3 1TB) always crash while transfering files into it.

It says "An unxepected error is prevening you from copying the file. If you keep getting this message, you could use the error code to search for help. Error 0x80070037: The specified network resource or device is no longer available.

I tried changing the USB driver as you mentioned but it didn't work.

I updated the modded driver with the latest from Intel:

Enjoy!

PS this is for 64bit only!

Using your guide I can't update the driver.

I've Win 8 64bit
