The standard LTO, which is about storing data on magnetic tapes, is far from dead. The companies part of the consortium, namely HPE, IBM and Quantum, have in fact published one new Road map covering another five generations. The goal is to arrive with generation 14 to offer up to 1.44 PB (i.e. 1,440 TB) of compressed space for each cartridge, which is 32 times what is available now.
Archiving to tape will live on for at least another 5 generations
It seems almost anachronistic to talk about tape storage nowadays, but this technology is still constantly evolving and still offers one of the best ratios between available space and price, as well as great reliability. Precisely because of this, manufacturers saw an explosion in sales in 2021, as he reports Blocks and Files.
The future of the LTO standard also looks rosy from the point of view of technological evolution, with manufacturers expecting to be able to double the capacity with each generation. It should be noted that for the current one, which is the ninth, the doubling plans have skipped and went from an uncompressed capacity of 12 TB to one of 18 TB. It is therefore not unlikely that this will happen again in the future, particularly given the problems in developing increasingly advanced materials (and heads for writing and reading) and in maintaining backwards compatibility with existing standards.
The LTO consortium is also focusing heavily on what it claims to be the greater sustainability of tape than discs magnetic platters: once written, tapes require no additional power and, if stored properly, can last for several years without data loss.
