According to Jeff Bonwick, one of ZFS&#x27;s lead developers, it did change. He discussed this point in detail (<a href="https:&#x2F;&#x2F;blogs.oracle.com&#x2F;bonwick&#x2F;en_US&#x2F;entry&#x2F;you_say_zeta_i_say" rel="nofollow">https:&#x2F;&#x2F;blogs.oracle.com&#x2F;bonwick&#x2F;en_US&#x2F;entry&#x2F;you_say_zeta_i_...</a>), however I&#x27;ll just quote the last couple of paragraphs for brevity:<p>&quot;<i>But zettabyte wasn&#x27;t perfect, actually. We (we were a team by now) found that when you call it the zettabyte filesystem, you have to explain what a zettabyte is, and by then the elevator has reached the top floor and all people know is that you&#x27;re doing large capacity. Which is true, but it&#x27;s not the main point.</i><p>&quot;<i>So we finally decided to unpimp the name back to ZFS, which doesn&#x27;t stand for anything. It&#x27;s just a pseudo-acronym that vaguely suggests a way to store files that gets you a lot of points in Scrabble.</i>&quot;
