I've got an application which requires data recording in a outdoor environment, and I am interested in the reliability of SSDs vs HDD when placed in a cold (down to -20) and hot (+50) ambient environments. Intuition leads me to believe SSDs will be more reliable, with the possible exception of high temperatures. Air conditioning enclosures is not an option.
Does anyone have any information on disk reliability in these situations?
Answer
Look for an industrial or ruggedized SSD for this application.
A good example of a proper product spec.
