Something has to come.
There is still room for innovation.
There should be manual data redundancy. Especially, where data gets mirrored on different locations of the disc.
Eg. where the data gets mirrored in an interleaved way, where the first eg. 10000 LBA sectors get mirrored at the outer edge. The data is interleaved.
In that way, the data will never physically hit it’s mirror on the middle LBA, thanks to the larger diameter at the outer edge.
