ZFS is like really good snow tires in the winter. You can tell people with other tires how great it is to have really good tires, but they dont believe you until they experience the benefits for themselves. Or put another way, no one "needs" ZFS until they really need it, then they wont live without it ever again.

I switched to it after the 7200.11 firmware mess, where the drives reported successful writes but didnt write anything. ZFS would have caught that, my Adaptec card certainly couldnt have and didnt.

ZFS to the rescue again a while later when those (now firmware updated) 7200.11 drives started dropping after 15k hours of service. ZFS saved my data when two drives started failing in my RAID5 set at the same time.

All the weird minor problems that would cause random issues or performance issues for other file systems like flaky SATA cables, intermittent HBA/backplane ports, etc. ZFS catches them all and informs you.

Having been hit by bit rot, corrupted files, corrupted file systems, etc etc before switching, ZFS is fantastic. And there is something great about watching it scrub at >1GB/sec, verifying every single bit of your data.
