A useful comparison between SLC and MLC flash:
It gets even worse with TLC flash. This is getting increasingly common
in Micro-SD cards and miniature USB drives. We are down to 1000 write
cycles and a data retention time of 6 months. Flash media is getting as
unreliable and thus unusable as late 90s 3.5" floppies... :-(
That is VERY true. Consumer-level stuff seems to be "maximum bits/Hz
for the money, reliability be damned". Anyone who has any doubts should
price SLC media against MLC/TLC stuff. Of course, the public isn't
taught much about this at all.
Yes. And when it fails, "Oh, I'll just go buy another one."
The training is -perfect-.
And when you get on someone's case about it, they usually say
something like "Well I didn't know!!" ...as if accusing YOU of doing
something bad by informing them of it.
The public is seriously fucked, and they seem to be pretty happy about it.
So...where can we get older long-life-expectancy flash drives? I
don't care if they're less capacious; I need to sneakernet small groups
of files around occasionally, not swap copies of my entire movie collection.
