Em primeiro lugar, é um mito que os SSDs se desgastarão, especialmente para o uso típico de desktops. Mas de qualquer maneira:
De outra pergunta de superusuário:
In theory, it is possible to read data even after all program/erase (p/e) cycles have been used up. In fact, the JEDEC specifies that data on consumer-grade SSDs should be readable for one year after all p/e cycles have been exhausted. So the likelihood of losing data due to the drive reaching the end of its lifetime is small; it's more likely that you'll have replaced or upgraded your system by then.
E aqui :
Second, when an SSD is allowed to run right to the end of its useful life, most controllers put the SSD into a “Read-Only” state that allows the operator to remove the SSD, copy its contents onto another device, then re-start operations in the shortest amount of time.
Você não pode escrever nele, mas poderá copiar seu conteúdo para o próximo SSD / HDD (por um período de tempo razoável).
