After going through life with a 2011 Macbook Pro 13.3" model a1278 that had really slowed down over the years, I finally pulled the trigger on a SSD. After installing this one: WHY DID I WAIT SO LONG? For the record I upgraded my RAM from 4 to 8 GB at the same time.
Before I installed this SSD it took my Pro almost 22 seconds to open Powerpoint, not to mention things just seemed to run as glacier speed.
Now? Woo baby, I'm opening PowerPoint in 5 seconds, and switching through apps in speeds that make me feel like I just bought a brand new 2018 MacBook Pro. I was considering it too, before remembering I could just upgrade my RAM and hard drive for 1/12 of the price, not to mention having better RAM and hard drive specs than what is currently being offered in entry level Pros! The only factor that had kept me from pulling the trigger all this time was the fact that I was a bit nervous about doing the replacements myself. Easy as ever! One of my best decisions I've made lately. This upcoming semester I won't be lagging behind in lectures because my laptop can't open up Word and PowerPoint fast enough!
P. s their support team was available all the time :)
