I am using Windows 8 64-bit and I have several USB thumbdrives. Whenever I try to copy files to any of them, the transfer starts out at about 17 MB/s, then goes to 19 MB/s, then drops to 5 MB/s and bounces between there and 3 MB/s. I have just updated my drivers and my computer has fairly new and fast hardware. These speeds are intolerable and I was wondering how to fix it.
I downloaded TeraCopy which has a precise percent progress bar, and I noticed that the transfer will start and stop, stuttering. About 7 MB will get transferred, then it will stop for about 2 seconds, and resume for 7 MB, and stop, until it's finished.
It should be noted that the rest of my computer is not slow at all, just copying to a USB drive takes an inordinate amount of time. I have looked at many of the related questions and cannot find any help.
I have tried using Device Manager to "Optimize the drives for performance" but that helped absolutely none. Some drives have a FAT32 filesystem, some have an NTFS filesystem, so I don't think that matters.
It seems like transferring to a USB stick used to be faster on my computer. Any ideas what it could be?
