    OK, vaste sujet. Apparemment, les stats de durabilité n'existent que pour les HD, SSD, quoique je puisse chercher un peu plus sur des sites comme TechReport our AnandTech.

    En demandant à cGPT, on obtient les infos suivantes en anglais. Je suis globalement d'accord avec ce qu'il donne. Etant donné la techno utilisée exactement, le support, et le degré de miniaturisation, ce n'est pas choquant, mais dire qu'une SDcard est la même fiabilité qu'un SSD, je ne le pense pas. Les meilleurs SSD industriels égalent/dépassent les HDD en durabilité, semble-t-il.

    Final Notes:
    - SD cards and USBs are great for light, removable storage, but not for critical or high-write workloads.
    - HDDs are still good for mass storage where speed isn’t essential.
    - SSDs offer the best all-around durability and reliability when used within their write limits.

    ============================================================================

    Feature / Medium SD Card USB Drive HDD SSD
    Write Endurance Low Low–Moderate High High
    Data Retention Moderate Moderate Moderate–High High
    MTBF / Reliability Low–Moderate Low–Moderate Moderate High
    Durability (Physical) High Moderate Low High
    Best Use Case Cameras, IoT File transfer Large storage OS, high I/O apps
