+encryption, compression, snapshots, and (meta)data checksums.  It can use
+multiple block devices for replication and/or performance, similar to RAID.
+
+In addition, Bcachefs provides all the functionality of bcache, a block-layer
+caching system, and lets you assign different roles to each device based on its
+performance and other characteristics.")
