Large data pool storage

So just like the title says. We're talking 5TB and more in overall data storage. I know zfs and TrueNAS is up for it but I wanted to hear from some real-world users to what are your thoughts and experience with multi terabyte storage for all the things in TrueNAS. SMB business production environments a plus. Also I can't help myself, HELLO WORLD! Hoping this is home for the foreseeable future ✌️
