SSDs aren't great for long term archival since the nand needs to periodically be refreshed. You can build a better SSD, but that compromises storage capacity. HDDs are better, but they have other issues from sitting around not being used. Disks like these are a pretty good backup method if produced correctly. If is the big key, 100 layers sounds like a lot of layers to manufacture correctly, and you won't know your dat is gone until it's unreadable.
But will it be able to replace tape for long term backup? LTO 9 is supposedly available, and up to 18TB not compressed. LTO-10 is 36, and supposedly LTO-14 is going to be 576 TB but that seems overly ambitious.
