ZFS doesn’t require more RAM (or at least not meaningfully more), it just uses it if you have it. The RAM/ARC can be turned down in the configuration if you don’t want it to do that. I think on Linux other filesystems just use the native Linux RAM cache instead(?), so it’s basically the same thing as ARC, just less prominent? Also, doesn’t ZFS have RAIDZ expansion now? Actually a lot of this article smells funny… probably because they just happen to know more about BTRFS. Doesn’t BTRFS still have the RAID5/6 write hole? I wonder what sort of setup they’re using if they’re running it on a NAS.









I was looking at point #3 from the article, which is more misleading in this area than point #5.
