    Hi everyone,

    I apologise if this has been discussed elsewhere, but I am unable to find it.

    When choosing a storage solution based solely on the least amount of heat/temperature and power/energy consumption.

    Would you choose Flash Storage SSD or HD 7200rpm?

    The SSD will unquestionably use less power and generate less heat than the 7200 RPM drive.

    I'm answering my own question here:

    SSD (Solid State Drive)

    Power Draw - Less power draw.
    Noise - No moving parts and as such no sound.
    Vibration - No vibration as there are no moving parts.
    Heat Produced - Lower power draw and no moving parts so little heat is produced.
    Magnetism Affected? - An SSD is safe from any effects of magnetism

    HDD (Hard Disk Drive)

    Power Draw - More power draw.
    Noise - Audible clicks and spinning can be heard.
    Vibration - The spinning of the platters can sometimes result in vibration.
    Heat Produced - HDD doesn't produce much heat, but it will have a measurable amount more heat than an SSD due to moving parts and higher power draw.
    Magnetism Affected? - Magnets can erase data.
