Comment on Hardware raccomandation for new selfhoster

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.

Hard disagree, and it is one of the best things about ZFS. You can plunk a ZFS pool on another system and be almost certain it will import. Systems die. Having been through several data-loss incidents, I find it is much preferable to be able to pull 1 disk than have to drag out 2 or three to transplant a ZFS pool.

Regarding the scrubs, I was trying to indicate that ZFS is more than just a raid manager, there are advantages to ZFS on even a single disk.

If that were entirely true, striping would be the most popular ZFS pool arrangement, since you get performance and max storage.
