Electronics in particular suffer "bathtub" curves of failure.
They have a high tendency to fail in their infancy, but once through this initial period will work fine for years and years until finally old age gets to the components and the likelihood of failure increases again.
I have had new drives (back in the 2tb era) fail before competing the raid rebuild and have to go back. These were seagates that I bought locally as internal drives luckily. So far no out of box deaths on any of the schucked externals off amazon thankfully.

Those were likely Seagate 7200.11 series drives. They were terrible - I had one where the drive failed in a few days and the replacement then failed in a week. After that, I refused to accept a 7200.11 as a replacement for a failed 7200.11, as I had seven of the 7200.11s, six of which failed in less than a year. I still have one 7200.11, but it has not been powered up for many years and I expect it will fail if I use it much. Fortunately, the next Seagate model was much better, and replacements from that series lasted Ok, but for a number of years I did not buy any more Seagate drives. Interestingly, I have three 7200.10 500 Gbyte drives all still working, one of them 24/7. They were obviously well built, and have lasted. But when Seagate tried to make the 7200.11 drives cheaper to produce, they really screwed up. And still their cheap non-24x7 rated drives have a fairly high failure rate. But their enterprise class drives seem fine.
