5 disks every 7 year on average have a cost (today) of 80/90$ per disk of 1TB. A 2TB Google One plan is 10$/month. In 7 years will be 720$ vs 450$. Yes you need to factor in the rest of hardware as well (but you can also use it for other things). So self-hosting is probably a bit more expensive but not that much, and you keep your data with you. In any case a NAS with 5 disks is probably overkill for family photos and videos, a single disk or at most a RAID0 with 2 disks over a RPi5 will be enough for many people and way way cheaper than a 2TB plan, but obviously you need to know how to and like to self-host
