Please note that the JDM series uses different chips from Mac's native SSD, meaning the JDM855/850/825/820 may reach 60~70℃ when in operation, but it'd still be well within the bearable range for the JDM. Also, users may rest assured that JDM's built-in thermal protection mechanism will be activated automatically to ensure proper SSD functionality.
