https://docs.mongodb.com/manual/reference/write-concern/ there is a word "memory". What type of memory they mean volatile memory (RAM) or non-volatile memory (on-disk/SSD)?

Hi Kęstutis,

In this context, "in memory" refers to acknowledgement of writes in RAM (volatile memory) and "on-disk" refers to acknowledgement of writes persisted to files in the storage.dbPath (journal and data files).
