ZFS: Apple’s New Filesystem That Wasn’t
It's kind of a shame that ZFS hasn't seen better adoption, and that btrfs has been pretty stagnant, and that in general next generation file systems are mostly still-born.  It would be nice to see some improvements in this area as 10tb hdd's are eminent, and data management is important.However, it's worth noting that RAID, especially in software on systems without ECC ram is less than ideal.  Beyond this is the overhead of managing larger filesystems with ZFS.  The DIY raid servers that support it have had some troublesome issues that I've experienced first hand.It's likely a lot of these advantages have been displaced by the discontinuation of Apple's server projects as well as other fears.  By similar note, I've always been somewhat surprised that NTFS hasn't been more popular for external media, as it's a pretty good fit there.In the end, software at this level has been held back significantly by the patent hornets nest that exists in the world today.  I truly hope that we can see some reform in this space, but with the likes of TPP and similar treaty negotiations around the world today, that is pretty unlikely.  Eventually some countries will have to strike out, break these bad treaties and reign in IP law.  The vast majority of software is undeserving of patent protection.  Just as software really shouldn't have copyright law that lasts for decades.  It's a shame all around.
