Today from the “What am I doing with my life?”-department: I finally set out to find a definite answer to something I’ve always wondered about ever since hearing about the deduplication feature of ZFS – does it work on the intros of TV shows? TL;DR: Nope!
I never even expected it to work. Plus, you’re always advised against using deduplication anyway. The infamous “1GB RAM per 1TB storage in the pool” rule which is often incorrectly applied to ZFS in general stems from it. So even if I had found out that it worked, I probably couldn’t have benefitted from that. But still, not knowing for sure always bugged me.
