Question: Are SSDs less prone to failure than traditional hard drives in a more humid and hot environment?
Answer: Going off this post then Yes
This is the explanation given:
?
With no moving parts, SSDs are not ?susceptible to the same shock and ?vibration limitations that can damage ?or degrade spinning disk drives. And ?because air density does not affect ?them (as with HDDs) they can operate ?at higher altitudes. Additionally, ?many SSDs are more tolerant of extreme ?conditions such as dust or moisture ?than traditional hard disk drives.
This is supported Here
?
Some environments are too hostile for ?a drive with a spinning platter to ?survive for long. The mechanical drive ?is too susceptible to damage from ?moisture, dust, vibrations, shock, and ?extreme temperatures. In sharp ?contrast, the solid state hard drive ?will survive more easily in all of ?these environments.
