Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.

I'm asking why it would be more reliable if it has the same vulnerability to being corrupted.

Right, but if the checksum is corrupted...

Yes Mr smarty pants, if all copies of data are corrupted the data is lost. More redundancy is more protection.
