Yeah, usually by the time you know a specific model is or isn't "good" the mfg has changed production or how things are laid out in the products themselves. Over time, you can glean that some mfg have been better or worse overall than others though, but that's not a promise of future efforts.
All the same, it's definitely cool and interesting to see. I've had some good and some very bad luck with storage drives over the years. I still think twice about Seagate drives since I had 6 out of 8 of their 3tb enterprise models go bad relatively quickly a decade and a half ago, specifically bought through separate vendors. I also had the first IBM Deskstar drives, the second died before the first could be RMA'd (raid1 isn't backup).
