The author mentions that he only evaluated drives that have some form of power loss protection - doing some quick searching around, I couldn't find any Samsung drives in the given price range that claimed to have that.
Did I miss an appropriate Samsung drive in my quick searches? Or is there reason to suspect that a Samsung drive that doesn't claim to have power loss protection would nonetheless handle this case better than the non-Intel drives that did make that claim? Because if not, then I don't think not evaluating Samsung drives compromises the results in any way.
The conclusion "buy intel" makes no sense. He tested far too few drives to make that conclusion, and many potentially safe alternatives went untested. Not to mention the fact that not all intel drives apparently are safe.
So yeah; it's unfortunately bogus science - he's drawing invalid conclusions from a far too small sample.
Terrible science = small, restricted subject population, from which an ironclad blanket conclusion is made, that covers the entire population.
One of the restrictions is price, which makes little sense in concluding so strongly for a measure involving quality. Not to mention that only a single specimen of a single model of each brand was tested. The top-voted comment in the thread points out some Intel models that don't have supercapacitors in them.
Already the article is updated with a couple of other drives to test. I guess that wasn't "End of discussion" after all...
Spoiler: He only tested these five drives, only Intel survived, so if they are your candidates, apply his conclusion:
Notably missing is the Intel runner-up Samsung and probably others i'm not aware of, as well as other models.
