The solid state drive is a very fast boot drive. I added a 5TB USB 3.0 for storage of files. It's been about a year. I am very happy with the computer. I feel I got a great value. The only thing I would change and will change on my next computer is get the larger case system, I would add an extra fan, I have a desk with a small space for the computer than does not have much air flow. I have to leave the door to the space open when I use the computer.
