Re: Memory tables safer for session tables?

Assuming that "secure" means here the un-accessibility of the data for unauthorized people, I think MEMORY tables are more secure. While disk based tables are accessible via the filesystem and could be copied into another MySQL database, MEMORY tables are accessible within the address space of the process only. The latter could be copied too, but finding the data within it is definitely more complicated than using the table files on another database.

However, MEMORY tables are an option only if the session info does not need to survive server shutdown/crash.
