Yeah that makes sense. I’d rather not go through trouble of re-dowloading all of my stuff once you get above like a couple TB. I’ve got an old RAID5 running 6 3TB disks I bought used. I’ve had 2 fail (SMART prefail, not completely) over the past 5 years. For me, the money I saved on used disks let me buy more and still keep it protected. As with everything, it all depends on what you’re willing to lose.
