But the opportunity cost is never having a true enterprise class file-system. If you look at Linux, OpenSolaris (and it&#x27;s derivatives), BSD and yes even modern Windows in terms of core technology and performance their file-systems are generations ahead of OSX. What shocks me is that given the BSD lineage of OSX that is hasn&#x27;t switched to ZFS yet given how Apple prides itself on being the &quot;best of the best&quot; of computing world.<p>But you want your mdfind and Spotlight so you have to be okay with giving up ZFS or another enterprise-class Linux&#x2F;UNIX file-system!
