But misleadingly easy as they might seem, there’s a lot of stuff going on inside that blank plastic case…and a lot of stuff that can go wrong. Unfortunately, most of that stuff requires either a certified repair or a complete replacement to fix.

There’s no straight-forward answer to this question; each buyer has different needs and you have to evaluate the decision based on those needs, your preferences, and of course budget. Even though the price of SSDs has been falling, the price per gigabyte advantage is still strongly with HDDs. Yet, if performance and fast bootup is your primary consideration and money is secondary, then SSD is the way to go.
