SSDs might fail rarely, but when they fail they do so grandly. Data recovery services typically charge thousands of euros even for the smallest drives.
Of course the cheapest data recovery technology is backing up in advance, and there are many services out there, but I'm not interested in "what ifs".
Sometimes a formerly working SSD isn't recognised at all by the motherboard, or seems not to be powered any longer, or has some other failure which prevents any interaction with it. In such cases, it's sometimes enough to replace a chip/controller inside, or something even simpler (which of course shouldn't be done at home).
Does any SSD technology, producer or line stand out as having a feature which probably or provably makes data recovery cheaper? Or vice versa one which is clearly the worst of class, neighbourhing planned obsolescence? (The former would be for instance a drive which is absolutely impossible to open without destroying it.)
