PARTIONING ENABLING LTFS | ENCRYPTION | WORM Note: Compressed capacity for Generation 5 assumes 2:1 compression. Compressed capacities for generation 6-12 assumes 2.5:1 compression (achieved with larger compression history buffer). Source: The LTO Program.

And we can expect that LTO tape will continue to provide excellent and ever improving cost/GB, reliability and performance for digital archives. What we can’t expect is that tape will be able to provide us with diversity in its supply and technology base.
