So I noticed that my videos that are on my external hard-drive get patterns of lag spikes in the sony vegas preview window, while video files on my pc's drive are completely fine. Is there any way I can fix this?
Chances are it is a bandwidth bottleneck. What kind of hard drive is it? USB 3.0? 2.0? How many clips at once are you editing, and what are the data rates of the clips? Even USB 3.0 drives max out at 5gbps, and many older USB3 controllers can't come anywhere near that, so it doesn't take but a few high bitrate clips to saturate your available bandwidth. Internal hard drives, especially the NvMe M.2 drives, are always going to give you better performance.

Thanks! I guess i'll have to copy them over. I believe the hard drive is usb 3.0 and 2.0 compatible is there such thing as a hard drive that won't lag?
If you use ESATA you can get 6gbps, which is the same speed as most internal hard drives, but otherwise use an internal solid state hard drive.
