This is not meant for human beings. A creature that needs over 140 TB of storage in a single device can definitely afford to run them in some distributed redundancy scheme with hot swaps and just shred failed units. We know they’re not worried about being wasteful.


Realistically, is that a factor for a Microsoft-sized company, though? I’d be shocked if they only had a single layer of redundancy. Whatever they store is probably replicated between high-availability hosts and datacenters several times, to the point where losing an entire RAID array (or whatever media redundancy scheme they use) is just a small inconvenience.
