Upgrading My Laptop

Yesterday I was browsing through YouTube videos when I came across a video about updating a laptop by changing the HDD hard drive to a SSD (solid-state) hard drive.  A SSD has no moving parts and runs much faster than a HDD.  It also cost more, but that cost has been going down just like other kinds of hardware cost go down over time.  I have looked at YouTube videos on how to install one, so I am going to be brave, or maybe foolish, and install it myself after I do purchase one.  Once installed, I should see a decrease in how long my laptop takes to startup and run programs.  Hopefully my laptop will be a lot more pleasurable to use with the increase in speed.  I will let you know how it goes.
