I’m with you on the first part but I believe that 2/4 PHP exploits have been observed in the wild.

JBOD = Just a Bunch Of Disks

RAID 0 with 7 disks is a funny thought. Maximum redundancy lol. … Edit: my brain broke for a moment and this has zero failure tolerance, 1 disk would break the whole thing.

Worth a mention that if you’re gonna do nested raid, 10 (1+0) has better fault tolerance than 01 (0+1).
