I just built a custom PC for video editing a few weeks ago and my friend helped me build a lot of it (I would've been lost otherwise). I store all of my data on my 4Tb External Hard Drive (WD Mybook) and back it up to another 4TB External Hard Drive. I make videos every week and have to upload a lot of footage to my computer. I store it all on external drives so I don't slow down the actual PC. Every time I go to transfer data from my 32gb memory stick to my External drive, it takes about 2 hours to transfer 5gb of data. I've tried other USB slots on my computer and not much of a difference all around. The highest I got up to was 3.5 MB/s. When I originally transferred all my files to my external drives it was up in the hundreds. I need help figuring out what caused the file transferring process to dramatically slow down. I even tried file transferring to my SSD to see if it was my External drive and it is also going terribly slow. Any help would be greatly appreciated!
