Mechanical hard drives are mainly a thing of the past in the mainstream market due to performance or lack thereof. In a lot of cases people will say their computer is slow thinking it’s a CPU issue or age issue when in fact its just a drive that doesn’t perform well anymore. We upgrade these with Samsung SSDs (Solid State Drives) and in most cases the computer would actually perform better then the day it was purchased as well as you can pick up exactly where you left off.
