ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it’s inflexible; it lacks modern flash integration; and it’s not directly supported by most operating systems. But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment. Here’s why.
Although not discussed in today’s keynote, Apple is adding a new “universal” filesystem to iOS and macOS. Apple File System (APFS) will likely replace HFS+ as the default filesystem for Macintosh computers, iPads, and iPhones and brings a wealth of modern features. But judging from the initial developer documentation, that’s not going to happen for a few more years. And there’s still much confusion about how APFS and CoreStorage, introduced in Mac OS X 10.7, will interact.
