Backblaze regularly releases failure rate statistics of their drives, and it's often a big enough dataset to be quite meaningful. I haven't been keeping up with it lately, but there certainly was a period of time where there were substantial differences in the failure rates of different manufacturers.
So while you do still need to have drive failure mitigation strategies, buying more reliable devices can definitely save you time and headache in the future by having to deal with failures less frequently.
It's impossible to tell how meaningful Backblaze's numbers are because we don't know the global failure rate for each model they test, so we can't calculate the statistical significance. Also there are other factors involved like the age of the drives and the type of workload they were used for.
That's a recipe for sorrow. Don't waste time on "reliability" research, just plan for failure. All HDDs fail. Assume they will and backup or replicate your data.
All SSDs will die too. Not saying you meant or implied that they wouldn't, just clarifying for anyone who may not be aware. You're spot on with "plan for failure".
