Whenever I am streaming/copying to of from/any conceivable action with an external hard drive, my kernal_task process eats a huge amount of my CPU.

Right now I am watching kernal_task sitting at 30% to copy some files from a small external laptop drive onto my main disk. This problem is the same with a 2TB WD Essentials drive.

Not only does this cause everything else to slow down a little, but it also dramatically heats up my processor. Fans are sitting at 4K to keep the system at 50 degrees. :confused:

While I plan to move all of my media to internal drive(s) (ie not an external drive) once I upgrade to a 1TB internal drive, I am still wondering why this is happening. This does not seem logical.
