I’m looking for opinions regarding a home #NAS (which I plan to setup):

Independently from the manufacturer: do I really need > 2 disks (in other words more than RAID 1) for a home NAS?
Sure, the more the better obviously. But balancing the safety / redundancy with the device prices and the energy consumption, I doubt the larger devices are needed for this use case.

@basepair It really depends on what you are storing on there, how important that data is to you (or your family?) and what your backup strategy looks like. I'm running a super cursed setup (been doing it for years) that is just a NUC with an external HDD (plugged in via USB) 😬 But mirror that to an offsite backup (which has a two disk setup with Snapraid) plus I backup all my work and important files to (obviously) encrypted online backup other external harddrives. #yolo #KeinBackupKeinMitleid

Well, that mainly depends on your use-case. I started with a 1-bay, added a 2-bay, replaced both with a desktop 8-bay and replaced that with a rack 12-bay. Went from no raid, to raid 0, to raid 5 to now raid 6. Wouldn't want to miss the extra layer anymore.

@basepair that depends a bit on your redundancy requirements. The point of raid 6 is that there is a redundancy of 2 disks in contrast to raid 5. Why? Because in the case of failure of a single disk, the remaining get under additional stress: keeping the data updated plus the restoring of the new spare drive. This is where the system is most vulnerable and a second failure is relatively likely. This, having one additional copy (be it raid 6 or raid 1 with 2 mirrors) is a good idea (1/2)

@basepair especially for larger disks, that take significant time to recover. I had never had the situation that I needed the second level of protection, fortunately. It gives you however a good amount of silent sleep 😜.
But, yeah, in general and with a good backup strategy, you might drop that. It is your decision on how time-critical the data is.

@basepair glaube nicht an RAID in deinem Anwendungsfall. Je nach Nutzungsintensitätät und Synchronisieren (bspw 2 Wege synch Nextcloud mit Rechner) hast du eigentlich schon ein Backup und kannst auch gute ssds verwenden. Ugreen NAS ist aber auch echt ne gute Lösung. Halt n bisschen China aber echt gutes Konzept und relativ billig
