What is the best portable 5TB External Hard Drive for a PC?

I want one for my desktop computer to keep all my stuff on so my computer can be freed up for other things. I want something I can put all my photos and images that I keep. Right now, my desktop must have 50 folders on it as well as 150 images. All that stuff on the desktop surely slows my computer down. If I stick all that stuff on an external hard drive, that means my computer will work faster, and I can still easily access all that stuff, right? Who else uses one? While we are at it, how about an external CD burner? Who makes those?

Will this free everything up and not make it so hard - to use?
