Need to speed up file transfer

I recently built myself a new PC and I have been having an issue with copying files between storage spaces/drives on the PC. Whenever I begin a file copy/move operation, the speed usually starts out at a respectable speed (ie. 40-50MB/s) and then rapidly drops down and fluctuates somewhere between 50KB/s - 800KB/s, occasionally going down to 0KB/s for a few minutes. 

I was wondering if someone could point me in the right direction on troubleshooting this issue and help me find out what is causing the bottleneck. If anyone can help me with this issue, I would greatly appreciate it!
