MacZFS is free data storage and protection software for all Mac OS users. It's for people who have Mac OS, who have any data, and who really like their data. Whether on a single-drive laptop or on a massive server, it'll store your petabytes with ragingly redundant RAID reliability, and it'll keep the bit-rotted bleeps and bloops out of your iTunes library.

The completely free MacZFS provides absolutely all functionality, speed, and data integrity guarantee which are needed for personal and small enterprise use. We believe it to be one of the most advanced storage solutions for most Mac OS users, at any price.
