My experience with ZFS on my home NAS: started with 6 2TB greens, 1 boot, 5 raidz1, got 5 3TB greens in another raidz1. One of each failed, replaced. Recently got 6 8TB SMR drives in a raidz2.<p>Never used ECC ram, too expensive. No problem with LSI raid cards, or SAS backplane. Most important advice: People aren&#x27;t kidding when they say your zpool will slow down when it&#x27;s almost full.<p>Online resizing of md arrays isn&#x27;t reliable, my friend lost terabytes. ZFS is 10 years old, well tested.
