If OP can’t afford the storage for ‘just a bunch of disks’, then paying twice as much for 100% redundancy in RAID10 is doubly unaffordable.
Also, consider what is being stored here. It’s music files that we obtained from a torrent. We need sufficient raw performance to read a few megabytes per minute so we can listen to them. As a bonus, we may wish to upload the torrent again, and can use any spare capacity for that. What benefit are you going to obtain from your very expensive storage solution?
RAID6 can lose any two drives, but at most two. RAID-10 can lose only 1 drive with guaranteed no data loss. Losing two might lose the cluster, if you lose a drive and its mirror. Yes, if you’re really lucky, you can lose up to half, but ‘feeling lucky’ isn’t how we plan data storage. Doesn’t matter, we’ve got a backup - download the torrent again ;-)
Yeah yeah, I know RAID.
