User John Paul goes into detail about the benefits of ZFS, or Zettabyte File System, the chosen filesystem for FreeBSD and other operating systems like FreeNAS. He also gives a little bit of history behind ZFS, going back to the Sun times.

Today, we will take a look at ZFS, an advanced file system. We will discuss where it came from, what it is, and why it is so popular among techies and enterprise.

Even though I’m from the US, I prefer to pronounce it ZedFS instead of ZeeFS because it sounds cooler. You are free to pronounce it however you like.

Note: You will see ZFS repeated many times in the article. When I talk about feature and installation, I’m talking about OpenZFS. ZFS (developed by Oracle) and OpenZFS have followed different paths since Oracle shutdown OpenSolaris. (More on that later.)

What is ZFS? Why are People Crazy About it?
