Well its for faster speeds. So I dont get why you would do a backup on a more fragile but faster storage. You described in another comment that you have many other backups, which is awesome. So good on you for taking care of everything. But yhea, using the opposite of what would be better for backups seems a bit counterintuitive to me. And to presume that it doesn’t matter to use the more secure option because you have many other backups anyway, is also slightly weird since why bother in the first place then.
I don’t mean any hate, you’re doing way better than me. Can I ask how fast the RAID 0 gets? And how much it would be on individual drives. And how much data you have to backup daily.
Much respect for your setup, you’ve taken redundancy seriously and I doubt you’ll ever lose anything.
