How would I architecture Network Attached Storage? This is a sequel (1, 2) question.

I'm interested in setting up a home networking solution. One or more individuals would be able to access their accounts from any one of multiple Macs around the house.

Direct Attached Storage is one solution.

Here I'm pursuing the alternative, Network Attached Storage.


What hardware do I need for a minimal installation. Say two Macs are the "terminals". Is a third Mac needed as a server?
Presumably I need some kind of RAID disk. Can you confirm?
is macOS server needed?
You need a NAS server, not a third Mac
You need some standard SATA drives to mount into the NAS or buy one that ships with disks included
No
