The “on/off” switches in SSD’s are fragile and essentially break after too many read/write cycles. As pointed out, it’s a get what you pay for world and cheap SSD’s are just that… cheap. The expensive ones are more reliable because they actually make available only a portion of their total capacity, reserving the rest as replacements for such failures. Intelligent software within the firmware manages this so that the end user experiences a much longer device lifespan.
There’s lots of technical documentation for such. Google knows. Regards, > On Mar 7, 2021, at 18:15, Michael A.
