Having someone to carry like that is also peak :3

Portability is not really an aspect one needs to consider when it comes to a NAS. Performance hits? Z1 will have performance issues when running in a simple mirror (especially for writes), but with 4+ disks that reduces significantly.

Sure scrubs will take longer on a multi-disk array, but again for a home NAS, the goal is maximising data storage capacity without a major hit on performance, ideally being able to saturate the most common gigabit LAN connection and have some more bandwidth available for local processing.

You’re incredibly wrong on your assumptions here.

First of all, ZFS (the file system TrueNAS specialises for) is best used with at least 3-4 disks. The more the better. A dual disk setup for ZFS (or any other kind of RAID) is super wasteful.

Second, no, 4TB won’t be enough. You think it is today, but soon you’ll be downloading media Linux ISOs and quickly realise that even 16TB is a stretch within a year.

My recommendation would be going for at least 4x 4TB, but 3-4x 6TB or even 8TB would be probably preferred. And similarly, I’d rather overshoot the initial purchase rather than realise 6-8 months in that oops, the 2-4 disk system you got isn’t enough… Even if you don’t fill the bays, I’d recommend you go for at least a 4 bay system, but rather, for 6. Sadly, SOHO NASes aren’t designed with easy expandability down the line.
