Question Very slow USB 2.0 speeds (and terrible 3.0 speed for new PCIe card)

[Lands]

I've never been happy with my USB ports but I never realized just how bad they are until I've started upgrading components and testing.

I purchased a USB 3.0 PCIe card and the speeds seemed to be no better. So I downloaded Blackmagic and tested the speeds:

• USB 2.0 slots:
  • Write: 8-10 mps
  • Read 33 mps
    
• USB 3.0 card slots:
  • Write: 3-7 mps
  • Read: 60 mps

At first I thought the issue was the driver for the 3.0 card (and that still might be true) but:

1. I'd like to improve the old USB 2.0 ports which is terrible

2. I wonder if the problem causing the 2.0 issue might be bottlenecking the 3.0 card?

All help appreciated. Not really sure where to start.

Thanks

Sure, sorry. I was writing to a USB 3.0 thumb drive, but you asking a good question made me test it with an external HDD using Blackmagic:

• EXTERNAL USB HDD
• USB 2.0 slots:
  • Write: 28 mps (up from 10 on the thumb drive)
  • Read 33 mps
    
• USB 3.0 card slots:
  • Something is def off with the card because it won't recognize my portable HDDs but it will read a thumb drive. Says it's plug and play with Win 10 but with this old of a computer I don't think so.

  • Conveneiently the DL site for the manufacture is down: http://febsmart.com/download.php

That's slow for 2.0, correct?

...am I correct that 28mps for an external HD and 10mps for a thumb drive is very slow for USB 2.0? Something strange is going on it seems.

Ideas on what might be an issue?
