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.
Delivering Scalability and Growth for Generations
With introduced in 2000, LTO technology is currently in its 8th generation.
LTO-8 specifications support tape cartridge storage compressed capacity of up to 30 TB*, 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 for backward compatibility up to generation seven of the technology is to write back one generation and read back two generations. The current 8th generation LTO Ultrium drives are able to read and write LTO-7 and LTO-8 media, 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 ULTRIUM ROADMAP
Addressing your storage needs
With the growing importance of regulatory compliance — including the Sarbanes-Oxley Act of 2002, the Health Insurance Portability and Accountability Act of 1996 (HIPAA), and SEC Commented [NW1]
Rule 17-a-4(f) — organisations need a cost-effective storage medium that can preserve corporate data in a non-rewriteable, non-erasable and unalterable format. LTO technology has write-once, read-many (WORM) capabilities to ensure that your data isn’t overwritten and also help address compliance regulations. It’s designed to provide users with a very cost effective means of storing data in a non-rewriteable format to address compliance regulations.
The key features of LTO WORM are secure encoding mastered on the tape media at the time of manufacture.
- robust algorithms that use LTO Cartridge Memory (CM) in conjunction with the unique factory- written format to prevent tampering.
- ability to append data at the end of a WORM cartridge so users can take full advantage of the tape capacity.
- a distinctive two tone coloured cartridge to distinguish WORM media from rewritable media.

It seems that every day that a company experiences ransomware or cyberattack that exposes confidential or private information. That’s why recent generation LTO technology drives features one of the strongest encryption capabilities available to help protect the most sensitive data stored on tape cartridges.

Recent generations of LTO technology include a partitioning feature, which help to enhance file control and space management via Linear Tape File System (LTFS).
Partitioning allows for a portion of the tape to be reserved for indexing, which tells the drive precisely where in the tape a file is stored.The second partition holds the actual file. With Linear Tape File System, the indexing information is first read by the drive and presented in a simple, easy-to-use format that allows for “drag and drop” capabilities–just like using a thumb drive. Learn more about the benefits of partitioning in the LTFS section.
