    I have a new Toshiba laptop Satellite C850/05D with a blue usb 3.0 port
    it works at the faster speed with hard drives capable of 3.0 but I have tried to use 2 different flash drives 3.0 one from Emtec and a TDK/Imation 3.0 flash drive and the 3.0 speed is non-existent it just slows at 2.0 speed
    I contacted Toshiba and they said if the port is working for hard drives it must be okay and it could be the flash drives at fault
    I contacted TDK and they had no idea
    are some new usb 3.0 drives saying 3.0 but not actually delivering on the faster speed or is it some issue with the 3.0 drivers but I thought Toshiba would be aware of this?
    I just want to get some answers before trying a third brand of usb flash drive
    the flash capacity was a 16gb any hard drive over 250gb works fine

    do you know anybody else who has usb3 on their computer to see what the transfer speeds are like off your flashdrives & does not have to be win8 as can be win7 or earlier? i think it is a flashdrive driver issue & not fom the flashdrive makers but from microsoft.

    wish I did know someone with usb 3.0 but I don't
    googled the problem seems a few people are having probs I'm not sure if they are the same specific issue as mine but a lot of usb 3.0 speed issues
    the flash drives I used made no reference to being windows 8 compatible in fact they said windows 7 but I assumed they would still work fine (although in hindsight maybe I was wrong)
    I guess just play the waiting game to see what Microsoft do, and what the flash drive makers do?

    Unlikely your wrong! USB is an industry standard across all makes & models of computers,if a hdd 3.0 is faster for the same particular sized file on a hdd it would suggest the flash drive itself is the culprit for some reason,another reason which happens on my comp with usb 2.0 is occasionally it will be detected (flash or ext hdd) as a usb 1.1 or at least i get a message saying that it could work faster if i use a usb 2.0 port,which is stupid since they're all usb 2.0 ports,simply unplugging & reinserting fixes it,yes there was a noticeable increase in transfer speed when i did other than that i got nothing unless the flash drive is a fake & its actually a usb 2.0 in a 3.0 wrapper,ok stretching it now

    I have nothing helpful to add except more instances of odd behavior with USB3 and flash drives - yet the HDD drives are OK.

    USB CrystalDiskMark testing.
    Code:
    USB ver 3 ports locations:
    Motherboard, PCI card + front extension off PCI card.
    
    USB3 HDD: all perform same on all ports.
    USB3 flash: good on Mobo.and PCI card.
    USB3 flash: fail on front extension off PCI card.
    
    Normal writing of any large file to usb3 flash on the front usb3 port will fail.
    Either lockups or files are corrupted and flash drive has to be re-formatted.
    
    USB2 flash in front USB3 port functions OK.
