Samsung has finally got its 31TB SSD into manufacturing, catching up with Toshiba's similarly well-endowed SAS flash package.

The 30.72TB PM1643 effectively replaces the current PM1633a and its 15.36TB capacity limit, and is positioned as an enterprise SSD, although Samsung does tell us it can store 5,700 HD movies.
