The main reason SSDs will eventually fail is the fact that NAND flash can only withstand a limited number of read/write cycles. NAND flash is non-volatile memory, meaning it retains data even without a power source. When data is written, the data already stored in the cell must be erased first.
What would cause a SSD to fail?
SSD Data Corruption can Cause a Drive to Fail. Thus, Leading to Loss of Data. Solid State Drive failures can stem from bad sectors or virus damage. Also, expect SSD failure from short circuits and corrupt data.
