    Copying to USB Very Slow


    A few times a week I backup my data files to my extended hdd and my USB.

    Seems it take forever to copy to the USB. Very short time to copy to Extended hdd.

    I've tried deleting to old backup first so there will be no need to replace and files.
    That doesn't seem to be any faster than replacing the files.

    Any way to make to copy to USB faster.

  3. Windows 10 Pro Extremely slow Data Transfer and Complete PC becomes Very Slow

    I have the same issue with slow file copying but I do not believe it is software related. I have two hard drives and 1 SSD. If I copy from the SSD to 1 hard drive its fast, if I copy to the other hard drive it starts fast then drops to very slow or
    stops altogether. This is consistent behavior whether copying from the SSD or external HD or a USB. One of my hard drive works fast, the other starts fast, then goes very slow. I dont therefor think this is a Windows issue but more likely a setting in
    the HDD itself - but I have no idea what. Any ideas?

    Copying to USB Very Slow

    @JamesJoey

    James, there a lot of factors involved. Under the best of circumstances, an external drive will always beat a USB thumb drive. Most significant is the USB 2.0 versus USB 3.0. Your external HDD is most likely 3.0 capable, and I hope you are using a 3.0 port. A thumb drive, 2.0 or 3.0 cannot take advantage of the system write cache like an external can. The controllers and drivers are different. Many brands of thumb drives are simply not engineered for massive data transfer. They are geared more to saving pictures and small videos, like from a camera. Or they are used for installation media, where they are read only. Writing to a USB is very slow, and the cheaper brands are extremely slow. Unless you have formatted the USB thumb drive as NTFS, it comes as FAT32, and has a file size limitation of 4GB. That in itself doesn't really affect the speed, just what you can copy.

    There really is no way to make a USB thumb (stick, FD) as fast as an external HDD spinner drive.

    Hope this helps. There's a lot more to it, but basically....you can't force a USB to do any better than what it is.

    The file system is ntfs.

    I wasn't aware that so many factors can effect this.

    I looked at the properties.

    What is 'Ready Boost?'

    In your case, and in virtually all cases nowadays, Ready Boost will buy you nothing, and you probably can't use it anyway. The hardware/software out now is far superior to any advantage from Ready Boost. My opinion, avoid it. And if you are using an SSD, avoid it like the plague! Here's some info:
