He comprado un nuevo SSD. Hoy instalé Elementary OS Linux en el SSD. Después de eso, instalo smartmontools para verificar el estado de mi nuevo SSD. ¿Puede verificar si los atributos inteligentes son seguros para un nuevo SSD, en particular Total Lba escrito 66876697

66876697 * 512/1024/1024/1024 ~ = 32

32 GB escritos me parecen razonables.


¿Cuántos GB al día puedo escribir? Samsung dice 150TBW.

Depende de cuánto tiempo quieras que dure. Digamos 10 años y supongamos que la unidad explotará exactamente a 150 TB (no lo hará). Luego obtengo alrededor de 42 GB por día. Usted escribió 32 GB instalando un sistema operativo, por lo que puede instalar uno y un tercio de sistemas operativos por día durante diez años sin problemas previstos. ;)
