Three weeks ago I replaced all of my laptop hard drives with 1TB Samsung Evo 850 Solid State Drives. I have three HP Elitebook Laptop Workstations that I use in my business that range from 2-5 years old. All have i7 quad core processors and 16MB of Ram. All still are useful but the hard drives were simply slowing things down. Cloning the drives was very easy and replacing the drives was simple as well. Now all of my laptops fly and I haven't heard the fans turn on even once. No moving parts to create heat.
