Older drives show better durability? If you've been feeling like HDDs aren't built to last as long as they used to be, you're not alone. Secure Data Recovery's blog suggested a relationship between when an HDD was made and how long it lasted before failing. €6 We found that the five most durable and resilient hard drives from each manufacturer were made before 2015. On the other hand, most of the least durable and resilient hard drives from each manufacturer were made after 2015. Unfortunately, Secure Data Recovery didn't specify what it meant by "most." But it did point to HDD manufacturers pushing the performance envelope as a reason why HDD reliability may have dipped with more recent products. This includes size limits that cut "allowance between moving parts, appearing to affect mechanical damage and wear resistance."

The previous story also makes the intriguing claim that older drives have longer lifetimes than newer drives. The blog post from which they take this claim does not offer adequate explanation for me to be certain, but one has to wonder.
I'm guessing this is what happened: "we did a study of drives that failed in 2022 and found that drives made in 2007 were on average 15 years old when they failed, whereas drives made in 2020 were on average 2 years old at failure."
