What is ZFS? Why are People Crazy About it?

John Paul Wohlscheid over at It's FOSS takes a look at the ZFS file system and its capabilities. He mainly covers OpenZFS which is the fork made since Oracle bought and shut down Solaris which was the original host of ZFS. It features pooled storage with RAID-like capabilities, copy-on-write with snapshots, data integrity verification and automatic repair, and it can handle files up to 16 exabytes in size, with file systems of up to 256 quadrillion zettabytes in size should you have enough electricity to pull that off. Because it started development under a deliberately incompatible license, ZFS cannot be directly integrated in Linux. However, several distros work around that and provide packages for it. It has been ported to FreeBSD since 2008.

    If you do a lot of Mac + Linux, ZFS is amazing. Once you have drivers on both, you can export a RAIDZ multi-disk JBOD USB3 enclosure from a Linux machine, plug it into a Mac, and it pretty much "just works". Dual boot works great, too. Network replication is dead simple.

    I started using ZFS for the cheap RAID functionality, but have really fallen in love with the benefits of root-partition snapshots, compression, and SSD-cached performance.

    The only big issue I have with ZFS on Mac and Linux is the lack of trim support.
