H-RS880-uATX (Aloe) and USB 3.0

Help please -

I have tried LaCie USB 3.0 and Western digital USB 3.0 eternal drives with Buffalo and WD pci USB3.0 cards and cannot get much higher transfer rates than I do with a USB2.0. and an HP Pocket drive. Im getting nowhere with any of the manufacturer's service techs.
Should I be able to get (realistic) 3.0 speeds withthis motherboard if I have a USB 3.0 card installed? Is there anything special I need to do to make this happen?

thanks in advance,

  1. You should be able to get significantly better than USB2 speeds, even if you don't get full USB3 speeds.

    What is the rated speed of the drive? The most likely problem is simply that the drive is slower than full USB2 speeds, so sees no difference.
  2. Thanks for your reply! Both drives are 7200 rpm.
  3. I meant MB/s, but as they are HDDs, there is no way that USB3 will give any real speed boost.
  4. I'm now using a Verbatim drive and pci 3.0 card and have the same results. How do I find the information on "speed" that you are asking for?
  5. Time copying some files to it or from it when using USB3 and USB2 to see if there is actually any difference. Most likely, the speeds are not much over USB2 speeds, if any, in which case USB3 will not be an improvement.
  6. 2.0 - 16 - 19 MB/sec
    3.0 - 17 - 24 MB/sec

  7. Both speeds are below USB2 speeds (48 MB/s), so it is the drive itself is too slow to benefit. The speedup from USB3 is probably because of either lower latencies or cache.
  8. Thank you. I'll check out the latencies and cache and see what I'm dealing with and make changes if necessary. This is new territory for me. I appreciate your feedback.
