: [[SGI]]’s high performance journaling filesystem that originated on their [[IRIX]] (flavor of [[UNIX]]) platform. XFS supports variable blocking sizes, is extent based, and makes extensive use of [[Btree]]s to facilitate both performance and scalability. Additionally, support is also provided for real-time environments.

'''Cryptographic file systems,''' also known as encrypted file systems, encrypt information before it is stored on the media. Some of these file systems store encrypted files directly. Others are better thought of as device drivers, which are then used to store some of the file systems discussed above.
