Wanted to increase the startup speed of my (late) 2011 Mac Mini as well as using the original drive as additional storage.
The upgrade process went very well overall.
If you wear X-large gloves in the winter (Big Hands) be prepared to be a little frustrated trying to reattach the cables (power, Video, IR ect.) they are incredibly tiny. Take your time, you definitely do not want to rush!!
