At least in my experience SSDs are literally the only part that tends to fail.

Using a used SSD( Refurbished assuming direct from manufacturer might be ok) feels like digging though someone else's stuff.

Maybe they cleaned it, maybe they left business docs or other sensitive data. The risk to reward is too great.

Having IT roll up into me, I've seen way, way more batteries fail than SSDs. Screen failure [and hinge failure] is far more common than SSDs failing. Keyboard/touchpads fail more often. Charging bricks/cables also fail somewhat more than SSDs. Beyond that, in the low end of the laptop re-use market, "just blindly always buy and install a new SSD" breaks the economics pretty badly.

Look at the SMART stats, format the drive, and install your OS. For people shopping laptops under $250, that seems like a better path than a new SSD.

What's the risk to you the user if it wasn't properly cleaned? Plug it in and format as the first thing you do if it worries you.
