Is there a similar post about LTO tape storage drives? I'm wondering how the newer generations achieve the insane transfer speeds and storage capacities.



There's quite a lot of similarity with how hard disks have dramatically increased their aerial bit density in that improvements in bit encoding and decoding techniques and DSP technology play quite a big part - actually LTO is behind hard disks on areal bit density as tapes have a different set of trade-offs as a removable media and archival format.


Not a post but half of the magic of LTO is the compression which doubles the speeds and storage capacity you see published.
