Solid State Drive – If your laptop has a mechanical drive, and most still come with one, this is the number one upgrade to increase its performance. Laptop hard drives come in 2 speeds: 5400rpm and 7200rpm. The 7200rpm speed is, as you would imagine faster. Unfortunately most manufacturers choose to go with 5400rpm drives due to cost.
Solid state drives are faster, much much faster, than either speed of mechanical drive. Replacing your mechanical hard drive with a solid state hard drive will drastically decrease the time it takes to load Windows, software, and even web pages.
A highly recommended upgrade for any laptop.
