A RAM disk implements a virtual disk in volatile memory. A RAM filesystem implements a virtual filesystem in volatile memory.

In other words: the difference between a RAM disk and a RAM filesystem is the difference between a disk and a filesystem.

So what then is the difference between a disk and a filesystem? To me it sounds like a box and a crate -- different word, same thing. Please elaborate. Danke! – Torben Gundtofte-Bruun Dec 1 '10 at 18:35
@torbengb: a disk is a physical device, i.e. hardware that stores unstructured 0s and 1s, without meaning. A filesystem is a data structure, i.e. software (very much like a database, actually -- in fact, a filesystem arguably is a database) that stores structured directories and files (and file metadata such as permissions, ownership, creation date etc.) which have actual meaning. – Jörg W Mittag Dec 1 '10 at 19:17
