Solid State Drives
One of the biggest ways to improve the performance of an older PC is to upgrade the Hard Disk Drive to a Solid State Drive. In new build PC's it is essential and the choice extends to the type of SSD - M.2 or Sata III. The latter is the more traditional type that plugs in using the same connector as a hard drive, but M.2 sockets are directly on the motherboard meaning the performance is better, and the internal looks are cleaner.
