If you have an old MacBook Pro with one foot in the grave, the single best thing you can do to breathe new life into it is to replace its traditional spinning hard drive with a solid-state drive. There's a reason that all modern MacBooks and the vast majority of all laptops sold today use SSDs. They are more energy-efficient, more reliable, and quieter than hard drives with magnetic, spinning disks. And they aren't nearly as costly per gigabyte as they once were.
I replaced my 2011-era MacBook Pro's 500GB hard drive with the 500GB Samsung 850 Evo. The whole procedure took less than an hour (not counting the half a day it took to clone my MacBook's hard drive to the SSD). Really, the hardest part of the whole thing was tracking down a size 6T Torx-head screwdriver for the four Torx screws that help hold the hard drive in place. (I found them at my local Ace Hardware.)
As you'll see in the video below, my colleague Sharon Profis resurrected her 2009 MacBook Pro with an SSD and agrees with me that the process is simple and straightforward. And hugely effective. So, let's get to it!
