What is LTO?
LTO is an open magnetic tape format developed to standardize the storage and retrieval of files for data backup, archive and transfer. The Linear Tape-Open (LTO) format is known for providing high-capacity storage, fast data transfer rates and long-term data retention. It is also known as LTO Ultrium.
The standard was developed through the cooperation between IBM, HP, Quantum and others. The consortium was formed in the late 1990s. The open standard format allows manufacturers to utilize the technology so that the tape format can be used consistently across all vendors. The standard was developed to move away from the complexity of proprietary tape formats used previously.

Are there multiple versions of LTO?
Multiple versions of LTO have been developed since its inception and release in 2000 called LTO-1. Each version developed increases storage capacity, performance, and scalability. LTO-9 was developed in 2021 and the expected release of LTO-10 is expected soon. LTO-9 holds up to 18 TB of native data per cartridge and 45 TB of compressed storage, and LTO-10 is expected to hold 36 TB of native data per cartridge.
