You should have announced it beforehand, so we could have given you input as
usual. :) I’m sure it will work just fine as temporary storage, but don’t
use it as singular backup device without, well, backup. Because I feel the
urge to dampen your mood by saying that the E100 is a very very cheap model,
if not the cheapest of all from any of the big named brands. It’s probably
still better than sticks, I guess.
The E100 just came out, so there are no long-term experiences available yet.
There has been a news item on my German hardware site on its recent release:
https://www.computerbase.de/news/storage/heimlich-eingefuehrt-ssd-serie-crucial-e100-erreicht-den-markt-im-tbw-tiefflug.91090/
Google-translated to English:
https://www-computerbase-de.translate.goog/news/storage/heimlich-eingefuehrt-ssd-serie-crucial-e100-erreicht-den-markt-im-tbw-tiefflug.91090/?_x_tr_sl=de&_x_tr_tl=en&_x_tr_hl=de&_x_tr_pto=wapp
The ghist of the article:
- It’s so low-profile there was no press announcement by the manufacturer.
- According to the article, it has a new record low for guaranteed lifetime
writes (TBW, terabytes written). The article has a nice table of
comparison with many other SSDs. The next best has more than twice the
amount.
- The (slighty harsh) comments speak of leftover recycling. The users are
hard-core gamers though, so the best is just good enough for them.
https://www.techpowerup.com/ssd-specs/crucial-e100-480-gb.d2306 mentions TLC
and no DRAM, though the computerbase article speaks of QLC (which is more
likely, especially given the TWB value). So don’t expect a speed miracle,
especially behind USB.
Another thing to consider: don’t put it into the safe for a year without
powering it up. As was explained in a previous mail, QLC uses sixteen
different levels of charge inside one single flash cell. The chance of a bit
flip increases the longer the SSD is powerless and charge slowly (very
slowly) dissipates. It’s hard to find exact numbers, and it’s more of a
statistical question. Could be a research topic for a slow Sunday. ;-)
Also, don’t you live in a hot area?
I don’t know if an SSD does a re-charge regularly by itself, or whether you
need to actually read out the cells for the controller to notice any issues.
This may be another good research topic. You could simply tar the entire
mounted SSD to /dev/null to read the entire payload once (without reading
the unused areas to save time):
tar cf /dev/null /path/to/filesystem/
