what's behind the infamous Seagate BSY bug?

As someone already mentioned, all HDD manufactureres produce some self-destructing junk from time to time. From my personal experience Seagate seems to be exceptionally good at this. However, I've also seen many cases of failed disks caused by choosing the wrong model/series usage-wise (mostly to save some bucks).

Those 15k disks had impressive specs in 2002  :-// Nowadays they are mostly loud and hot disks that are far outmatched by solid-state. A 2TB SSD can be had for 150EUR, and it runs circles sized many orders of magnitudes around any HDD in terms of performance, power consumption, noise and to some degree also reliability (given that you buy from a decent brand with solid firmware/controller).
You'd only buy spinning rust now if you need to store dozens of TBs. And then enterprise drives can make sense, because they come with extended warranty (5 years) and higher workload ratings. But I think they only make them at <=7200rpm speeds. HDDs for data density, SSDs for speed.

In the 12 yrs I've been using SSDs, I've only had 1 fail. And that was on day 1 in which the controller must have struck a bad FLASH sector.

Daily data backup is always a good idea. I run daily automated snapshots from my NAS and home server, which are stored outside the house in case any devastating disaster happens.

15K enterprise disks are still a thing.

I've been involved in the recovery of a few *large* arrays for organisations that thought they had a decent backup/recovery plan, it's also important to *TEST* the plan because it's no fun finding out your backup wasn't doing what you thought it was after your array has failed.

Have also had plenty of SSDs fail in use, one only a month or so ago, it's a thing

Caveat, I spend ~£500K-600K per annum on end user laptops alone and that's not counting the other equipment so I handle more IT hardware in a year than some people see in their entire life, those numbers alone ensure I see more failures too.
hans:
Good points. At the rates that I'm buying computer equipment, my failure rate can't reach a resolution below 5%.
I imagine there are users and applications everywhere. My comments are from a power user perspective.

A backup isn't a backup if you haven't tested it. Reminds me that I should run that test again some day. I mount my backup repo from time to time to grab some files I have deleted, so I know the repo is intact and gets updated. But I should schedule a complete recovery from scratch next time I reinstall my lab workstation.
Hypothetically, say my house has burned down, I just got a new laptop in and I want to login on my accounts again. See if I can get all my data back without using any local resources.

LOL what?  :-DD

Until a few years ago, CMR is all that existed! Basically, all else held equal, SMR is suitable only for low-writing situations, CMR can be used universally.
