I've got four of the Intel 5xx series here in the
office with no failures. Three of them are over a
year old.

A year isnt very long.

A year isnt very long.

It is if they are being torture tested during that entire year.

I've had one of my drives for over 425 days, and it's "only" had 11TB of
writes to it (and it's only a 240GB drive). So it's nothing compared to
the 700TB to 1PB of writes that's happened to these drives.

So 10 months under torture testing of writes is how long in years under
a normal load of writes?

Depends, but for a system drive, e.g. something like 10-100 years.
For a data-drive possibly longer.

Fantastic. My 64Mb USB is only 10 years old, and it still
works fine. Excited it might still be working in another 10 or more
years.

A USB flash drive is not the same thing as an SSD, even though they both
use flash storage. The SSD would have much more sophisticated load
balancing features, and much more redundancy.

His wasn't.

I was just pointing out that sizes get redundant much faster
than durability. Ten years is more than enough.

Another factor to consider it how long the data is retained;
consider both the case of un referenced data when the power
is on and all data when the power is off.

This is actually quite an important question.

If data are written to an SSD and that SSD is then unplugged, what is
the guaranteed retention time without corruption, of that data?

Hard disks are well known to suffer from "bit-rot", but do we have any
data on whether it's a problem on SSDs?

Not as long as books, then ;-)

It's kind of ironic that as we move through the most culturally and
technologically rich period of time (on earth), a good deal of our media
will, in the not too distant future, be lost. Perhaps.

It's safer than the library at Alexandria, though.

Just in case it is you can generate PAR files for anything important, so
minor bit rot is less likely to stop you recovering your files.
