Because I feel the= =20 urge to dampen your mood by saying that the E100 is a very very cheap model= ,=20 if not the cheapest of all from any of the big named brands. It=E2=80=99s p= robably=20 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= :=20 https://www.computerbase.de/news/storage/heimlich-eingefuehrt-ssd-serie-cru= cial-e100-erreicht-den-markt-im-tbw-tiefflug.91090/ Google-translated to English: https://www-computerbase-de.translate.goog/news/storage/heimlich-eingefuehr= t-ssd-serie-crucial-e100-erreicht-den-markt-im-tbw-tiefflug.91090/?_x_tr_sl= =3Dde&_x_tr_tl=3Den&_x_tr_hl=3Dde&_x_tr_pto=3Dwapp The ghist of the article: - It=E2=80=99s so low-profile there was no press announcement by the manufa= cturer. - According to the article, it has a new record low for guaranteed lifetime= =20 writes (TBW, terabytes written). The article has a nice table of=20 comparison with many other SSDs. The next best has more than twice the=20 amount. - The (slighty harsh) comments speak of leftover recycling. The users are= =20 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 TL= C=20 and no DRAM, though the computerbase article speaks of QLC (which is more= =20 likely, especially given the TWB value). So don=E2=80=99t expect a speed mi= racle,=20 especially behind USB. Another thing to consider: don=E2=80=99t put it into the safe for a year wi= thout=20 powering it up. As was explained in a previous mail, QLC uses sixteen=20 different levels of charge inside one single flash cell. The chance of a bi= t=20 flip increases the longer the SSD is powerless and charge slowly (very=20 slowly) dissipates. It=E2=80=99s hard to find exact numbers, and it=E2=80= =99s more of a=20 statistical question. Could be a research topic for a slow Sunday. ;-)=20 Also, don=E2=80=99t you live in a hot area? I don=E2=80=99t know if an SSD does a re-charge regularly by itself, or whe= ther you=20 need to actually read out the cells for the controller to notice any issues= =2E=20 This may be another good research topic. You could simply tar the entire=20 mounted SSD to /dev/null to read the entire payload once (without reading= =20 the unused areas to save time): tar cf /dev/null /path/to/filesystem/ --=20 Gr=C3=BC=C3=9Fe | Greetings | Salut | Qapla=E2=80=99 Please do not share anything from, with or about me on any social network.
