Do you trust consumer grade SSD to store back up?

(1/9) > >>

Rick Law:
I go back and forth with this one.  I have a couple of Crucial MX500 (500gb SSD) and a few Seagate Momentus (500gb  spinning disc).  Both are easy to connect up to do back-up, but from experience of > a decade ago (40 gb SSD), I found myself having difficulty trusting the SSD for long term (5 to 10 yrs) back-up.

What are your experiences with consumer grade SSD for long term (over 5 years) backup?

Zucca:
The first SSDs that show up on the market (2013-2014) were absolutely a horror movie!
Today things are different, they are reliable and all is good.

That said SSD or not there is only one golden rule: do regular backup on your data.

I have multiple backup on SSD, spinning and cloud for my crap.

rdl:
I doubt they're worse than anything else. They might be better. Right now what I distrust the least is good quality spinners. But I would say SSD is a very close second. I am using both for long term storage but I don't have any history yet with SSD.

I wouldn't rely on broad classifications to make such decisions, I'd look at the historical failure rates of specific models.  For me SSDs are only Samsung and not the old 840 series.  HDDs are various HGST models, the Samsung (now Seagate) 2TB 2.5" M9T (for laptop internal backup) and for big non-critical stuff (media) the 8TB Samsung 3.5" drives shucked from external enclosures.  The last are low-power, low-RPM and SMR, but so far so good. YMMV and it might pay to read the reliability reports from BackBlaze.

As far as time and potential bitrot, I've been running a Samsung 830 for 10 years and that computer is now only used occasionally.  No issues or errors.

It depends on the SSD technology.. With newer SSDs the endurance (number of writes per flash cell) decreases significantly (while the flash cell density increases significantly). You have to doublecheck the flash technology of your SSD. Moreover the flash memory cells consist of Leyden jars where the charge slowly evaporates, thus you have to consider the max flash cell retention time (usually 10 years).
