LTO Ultrium Data Cartridge

Linear Tape Open (LTO) Ultrium is a high-capacity, single-reel tape storage solution developed and continually enhanced by Hewlett Packard Enterprise, IBM and Quantum and promoted by the LTO Program. It’s a powerful, scalable and adaptable tape format that helps address the growing demands of data protection. It’s also an open format, licensed by some of the most prominent names in the storage industry to ensure a broad range of compatible tape drives and cartridges.


First introduced in 2000, LTO technology is currently in its 7th generation. LTO-7 specifications support tape cartridge storage compressed capacity of up to 15TB*, more than twice that compressed capacity over the previous generation, and tape drive data transfer rates of up to 750MB* per second for over 2.7 terabytes of storage performance an hour per drive. New generations have been introduced regularly with higher capacity and transfer rates along with new features to further protect your data and content.  LTO specifications provide backwards compatibility to read/write with previous generations. Current-generation LTO drives are able to read tapes from two generations prior and are able to write to tapes from the prior generation, so you know that your investment is for the long run.

*Assuming a 2.5:1 compression achieved with larger compression history buffer available beginning with LTO generation 6 drives.



LTO technology features a write-once, read-many (WORM) capability to ensure that your data isn’t overwritten and also help address compliance regulations.


LTO technology features strong encryption capabilities to enhance security and privacy during storage and transport of LTO tape cartridges.


Recent generations of LTO technology include a partitioning feature, which help to enhance file control and space management via LTFS.
