The bigger they got, the less reliable they became. I remember so well the early drives. They were bulletproof except for laptop HDDs, those were always crap in my experience.What happened with the brands that where so extremely robust? I still have 4x 160GB Samsung disks that work, after 20+ years lol. Seagate is the worst in my experience, and my personal problem is, it is been going on for years, the high failure rate those drives have. Never they have improved anything really and the failure rate of those things is still too high.
I used to run a HDD recovery service, varying from PCB swaps, MCU flashes, platter swaps, the whole thing. The brands that where always in by default where either seagate or WD, apart from the models that where dropped on accident.
Then there was that great flood in the biggest HDD factory which resulted in huge quantities of drives that were dying within first year of use. Then they improved a bit, probably because so many people got frustrated with high failure rate. I remember when well most hard drive companies dropped warranties from 3-5 years to one year. That was literally like a flashing "do not buy" sign.
I think we will never return to the early days of reliable hard drives. I think a lot of drives bigger than 4tb
are a lot less reliable. And my own drives prove this theory.
