Hewlett Packard Enterprise, IBM, and Quantum, collectively known as the LTO Technology Provider Companies, have officially announced the specifications for a new LTO-10 data cartridge featuring 40TB of native storage capacity. This update to the LTO Ultrium format delivers a substantial capacity increase and a retooled technology roadmap that aligns with current trends in AI-driven data use, long-term archiving needs, and sustainability concerns.
LTO-10 Data Cartridge
The new LTO-10 media can store up to 100TB of compressed data at a 2.5:1 compression ratio, making it particularly useful for enterprises handling massive volumes of information. As organizations increasingly rely on data for AI model training, analytics, compliance, and long-term preservation, demand for higher-density, offline air‑gapping continues to grow. The 40TB capacity represents a 33% increase over the existing 30TB LTO-10 cartridges, which will continue to be available and coexist with the new model.
The capacity boost is the result of engineering refinements to both the drive head and the tape material. Central to this upgrade is the use of an Aramid-based base film, a shift from the composition used in the earlier version. This material enables thinner, smoother tape, allowing longer tape to be housed in a standard cartridge shell. Importantly, no new drive is needed. The 40TB cartridges are compatible with existing LTO-10 drives, offering users an immediate upgrade path without requiring hardware replacement.
LTO Program Roadmap Updated
In parallel with the 40 TB announcement, the LTO Program has adjusted its roadmap for future generations of the Ultrium format. Generations 11 through 14 will feature revised capacity targets, with the final milestone now set at 913 TB for LTO-14.
These new goals reflect projected storage needs across industries and are designed to deliver better long-term value at a lower cost per TB. The roadmap also keeps future development aligned with reliability expectations and the growing need for scalable solutions.
At the same time, the offline nature of LTO tape remains a strong option for organizations seeking to enhance their resilience against cyber threats.
Availability
The 40 TB LTO-10 cartridge is expected to be available in the first quarter of 2026. Qualification and interchange testing will begin immediately. Buyers are encouraged to look for LTO Ultrium verification marks on both drives and cartridges to ensure format compliance. Organizations evaluating whether this new media fits into their long-term planning can use the LTO TCO tool or work with their preferred solution providers to assess cost and environmental impact.
