The LTO tape consortium (led by HP, IBM and Quantum) has a public tape product roadmap that will take magnetic tape technology out to about 13 TB of native (uncompressed) storage capacity.
The LTFS LTO file system allows modern digital tape storage to be used like NAS file systems and simplifies the use of magnetic tape libraries and allows faster access to the content stored on them.
In addition to a higher storage capacity than past LTO generations, LTO 5 also offers new architecture features such as the LTFS file system that turn magnetic tape into a directly addressable data source, like a hard disk drive.
