Wasn't it just the day before yesterday that Bill Gates famously said nobody would ever need more than 64 KB storage?
It /is/ amazing the progress we've seen in our lifetimes. I remember life before the web (http) was invented, before mobile phones (much less smartphones) became commonplace.
Some of the supposed 'progress' is really regression---like the number of people who economically could productively use computers but think a mainstream smartphone can let them do the same things. Sure, they can web browse, access online banking, ticketing, commerce, and other services through apps, but they usually miss out on the entire creative and productive side of computing.
However, I don't just blame technology. At least in Occidental countries, we tell ourselves we're consumers, vocabulary that hides the fact we're also producers/creators in our work. But it fits a mechanistic view of society, and works well with the central planners Utopian pretensions.
I love hearing of projects like the OPs---breathing new life into unused machines.
It was! It was exactly the day before yesterday when he said that. I remember.
I started my "career" doing "multimedia" in the 90s. Macromedia Director programming. I also remember those who had a 486 and that one guy who had 486DX. I remember seeing the "web" for the first time somewhere in 1994. I also remember looking at my friend asking if he thinks anyone will ever make money off this thing. We both said "Naahhhhh" at the same time and laughed.
I still finding it hard to trust 1TB worth of important data stored in that medium. I'm half joking but still, only half joking. The other half is dead serious.
You're right. SD lacks things like overprovisioning and wear leveling that would reduce failure rates. It's also rather slow to read/write from. On another note, it's incredibly easy to lose them.
It is always a bad idea to store any amount of important data on a single medium.
Seen too many (including myself at some point) have all their data in one external HDD and pass it around friends with a caution to be safe with their data.
I've lost most of my photo and video collection due to two HDD failures between 2017-2020.
SD cards for me is just a medium to transfer from a device to permanent storage so I don't have to worry about data retention on a tiny device unless it get lost.
