I’ve upgrade my laptop with a solid state hard drive. And whilst it may not be a big drive its bigger than the one in there already. And why would you want to change to a solid state hardrive? Well it speeds the boot up time loads, even if your running lots of programs on start up like I am. Hoping it will extend the battery life as there no longer a hard drive whirring all the time. But mostly just to make the laptop quicker like picking up a tablet device. The laptop is just way way quicker now, smart.
