And I went through dozens looking for one that worked. Ymmv.

Survivorship bias. Floppies failed all the time. Flash can be unreliable if you’re talking about the cheapest or abused the wrong way, but flash SSDs handled wisely are much better than hdds , which in turn are much better than floppies.

If you compare the thumb stick that came free from a convention then compare it to a floppy that came free with a magazine. And in the end neither matters because they’re both cheapest possible junk, not fair examples of the tech.

Similarly, the cheapest led bulbs (put in poorly ventilated fittings) have crappy lifetimes, but that’s not the techs fault, it’s because they weren’t engineered to last, they are cheap crap. Well designed leds placed sensibly are vastly better than bulbs, but that’s hidden by the cheap end of the market

That is the first I ever saw the term "mog" used outside of bodybuiy/looksmaxxing.

This is just flatly false. You're comparing a worst case SSD with maybe 10% of its writes left to an extremely lucky floppy disk that hasn't died to binder hydrolysis, mold and fungal growth, warping or demagnetization. And you also completely made up that you couldn't generate a strong enough magnetic field at home to corrupt one - you absolutely could especially since rare earth magnets are not that uncommon and are more than enough to kill a floppy.

"mog"?

There's flash, and then there's flash.

Say, the Siemens PLCs I earn my living programming uses SD cards which range from 64kB to, uh, 128MB, methinks.

They still work after decades, so clearly, you can get long term reliable flash storage; just don't expect to be able to store your 4k holiday videos on them.

NOTAMs, on the other hand? Go ahead!

I used to do floppy disk data recovery as a service for students at college. Roughly speaking, we helped one student out every three hours, out of 2,500 students, during busy hours. Based on the rates and hours, I think it would come out to something like 25% of the student body, each year, coming to us with a data loss incident involving floppy disks.

YMMV. I’m sure a lot of people were shoving these things into backpacks, and this was post-2000, so the quality of disks for sale was poorer than it was in the 90s and 80s.

I’ve also (since then, for myself) repaired drives. The drives fail because they’re mechanical and have motors, and anything that moves or has a motor in it will need some kind of service. Servicing a floppy drive requires specialized equipment which is hard to find (or requires a lot of patience—it’s possible to repair a floppy drive with just a screwdriver, but it’s not fun; guess how I know?)

3.5" floppies were still common while I was in college. I have distinct memories of copying a project to a floppy in my dorm room, popping the disk out, walking next door (literally next door in the dorms, not even going outside up or down stairs or anything), popping the disk into a team member's PC and the project being gone. We laughed it off and chucked the disk in the trash and got another. Project wasn't lost-lost since I had a copy on my hard disk. This was also the era of the 100MB Zip Drives, which I also had in my PC and thankfully all of our lab PCs had, too. That's what I normally used for all of my day-to-day file transfers of any real import. I still have my zip disks, but I seem to have lost my zip drive, so no idea if the disks still have any data on them.

Sure, but what are the odds they're using these rather than HD 3.5" disks purchased from whatever new old stock they've been able to source over the past 20-odd years?

and how many bits have rotted on those?

Of course some will last longer. It's not a cliff, just "not recommended to use for longer than...". But a lot depends on the conditions of storage, how much usage they got, etc. Manufacturers gave them 10-20 years normally, which puts almost all of them in the not recommended territory.

The fact people have old working floppies doesn't change the fact that degradation happens.

Why do you write it as “Apple forward slash forward slash E”?

The more expensive blurays are quite long lasting, being non-dye based.

Absent doing something wildly abusive, vinyl records will play fine for a long time. And the degradation is comparatively graceful.

Source: go to any used record shop and find a copy of Chicago >5[0]. It'll almost certainly play, even if the music wasn't particularly good to start with.

Ohhh, don't compare magnetic backup tapes to floppy. Same designs underneath but completely different storage shell, delivery mechanism, even the coating is different.

One cost $100 another $1.

Then these tapes are typically write once read many.

They were designed to deal with floppy disk flaws consumers deal with.

Actually really cool to read about modern tape systems.

I had a customer with a slightly dusty office and we simply gave up on tape drives as a backup storage medium because we were replacing the drives or tapes on a monthly basis.

We switched them over to external USB enclosures with cheap SATA drives in them and never looked back.

> And yet, there’s a reason we use magnetic tape for long term archive

Is it because "long-term archival" strategies aren't updated frequently?

50% of the time it works every time!
