RE: Playing digital from SSDs and USB flash drives...

Gold plating may be applied in varying thicknesses.
"When connectors are plated with a very thin "flash" gold deposit (less than 10uin, 0.25um) the gold is a very porous. The gold plating thickness may look continuous but there are thousands of microscopic pores in the deposit making it more like a thin screen of gold rather than a continuous pore-free layer. Although the gold plating may not readily react to corrosive environments, the pores in the gold provide a path to the base material which will allow the substrate to oxidize and corrode through the gold." https://advancedplatingtech.com/
