This article was originally written in 2015 but it is still relevant. I have just updated it given that SSD prices have dropped dramatically in the last 3 years. Upgrading the boot drive on my Mac Mini to an SSD drive was by far the biggest speed enhancement I’ve experienced on any computer! The speed increase is incredible – almost hard to believe. Boot time went from 60 seconds to under 30 seconds, and applications launch instantly – no bouncing dock icon. In terms of bang for dollar, upgrading to an SSD drive is by far the best upgrade you can do.
