That's where I thought I would get recovery....or are recovery and fault tolerant two different things?
Also, the cheapest 2 bay NAS I see on amazon is around $37. 4 bay NAS's don't show up until $200+. Does it matter if I get one 4 bay or multiple 2 bay NAS's?
I have to be careful now, because English is not my native language, and it looks like we don't understand each other.
Ok, I used fault tolerant and recovery almost as synonym and that is what I meant.
Again a NAS uses volumes, what is C: in Windows is a volume in a NAS.
If a volume is configured out of 2 physical disks and the correct RAID type is used, the NAS stores recovery information on all disks which makes it possible for the NAS to recover from the loss of a disk. I thought this to be fault tolerant
If you configure volumes consisting out of only one disk you can't do that, that is clear, and you can't recover from a crash, you will have to reload a backup. I thought this to be not fault tolerant.
NAS 2 bay at $37 or 4 bay at $200+
It should not make a difference, but have you seen what functionality you get? I only know Synology and it can do much more than file sharing: multimedia streaming, cloud functions, webfunctions.....
Hope this explains it a bit more,
