Not "consumer", but the only M.2 SSD with 80 mm length (M.2 2280) I found that has power loss protection is this one: https://www.kingston.com/en/ssd/dc1000b-d

I'm planning to replace it by the SSD linked above. I was already aware of the power loss issue on consumer SSDs (from the 2013 piece http://lkcl.net/reports/ssd_analysis.html http://lkcl.net/reports/ssd_analysis.html), but I wanted to see it happen for real. I guess I did now.
- wtallis 6y agoYou'll probably experience a lot more unplanned power loss in your laptop by giving it a SSD that idles at 1.2W instead of one that idles in the mW range. And there's a real chance that it won't even solve your problem.
