Hello,

 

This computer has no onboard USB 3.0 ports so I recently installed a USB 3.0 PCI-e card.   The drivers installed correctly.  I connected a USB 3.0 flash drive to it and it's recognized and files can be transferred to the drive.   The transfer speeds are no faster than the USB 2.0 ports.   

 

Someone mentioned checking BIOS, but I found no USB reference in BIOS.   I tryed suppying the PCI card with power from connector but no difference.

 

I've read many different places that it should be possible to do this upgrade and have faster speeds.    

 

Thanks for any suggestions...

Yes, not near what is advertised as USB 3.0 speeds.  However, considering that the hosting machine is from 18-Jun-2008 and you list Windows Vista as the OS, not terrible.  That old hardware must not be up to the task to be able to feed data to the USB 3.0 card and flash drive.

@Moogalani,

How are you determining the speed?  What program?    Did you use HDTune version 2.55 ?

In theory you are correct.  Please give the model number and make of the PCIxE card and the method by which you are measuring that transfer speed.

The card is a Rosewill RC-505. I'm measuring the speed based on what Windows is specifying when copying from hard drive.

About 2 mb/s for many files at once. 25 mb/s for single latge file.

The card posted is USB 3.0 as expected.  It also depends on the devies used during the testing.  As @wb2001 mentioned use HDTune or look at this

Also list the devices that are supposed to be USB 3.0 rated

OK.  That flash drive should be acceptable.  BTW: is that the only USB 3.0 device?

Yes, that's the only device.

 

I tried  the HD tune and the flash drive did get slightly better results on the 3.0 drive.  41.7 MB/s vs 30.

 

 

My goal is to backup a large number of files which slows down the speed to around 2.5 mb/s.

 

I guess thats as good as it gets. This is dissapointing considering how usb 3.0 is advertised.
