Fujifilm LTO 10 Data Cartridges: 40TB Availability in US

FUJIFILM Corporation has confirmed the availability of its latest magnetic data storage tape cartridge, the FUJIFILM LTO Ultrium 10 (40TB) Data Cartridge. The company announced that the new media began shipping in January 2026, marking a significant expansion in storage density for the LTO-10 generation. This release introduces a 40TB native capacity option, offering enterprises a higher density alternative within the same hardware ecosystem used for earlier 30TB media.

The new cartridge achieves a maximum recording capacity of 100TB per cartridge when using compression technology. For uncompressed data, the native capacity stands at 40TB. This specification represents an advanced iteration of the FUJIFILM LTO Ultrium 10 (30TB) Data Cartridge, which was originally launched in June 2025. By offering a second capacity point within the LTO-10 generation, Fujifilm provides customers with a choice between 30TB and 40TB formats based on specific cost and storage density factors.

Technical Enhancements and Compatibility

To achieve the increased capacity without altering the physical cartridge format, Fujifilm implemented specific changes to the tape material itself. The LTO-10 (40TB) cartridge incorporates the company’s proprietary fine hybrid magnetic particles to enhance areal recording density. The manufacturing process utilizes a novel thin-layer technology with Aramid film. This material choice reduces tape thickness, allowing a 30% increase in tape length per cartridge compared to previous iterations.

Despite the internal changes to the tape media, the external dimensions of the cartridge remain unchanged. This design decision preserves compatibility with existing drives. The new 40TB cartridge is compatible with the same LTO-10 drive hardware as used for the 30TB cartridge. According to reporting on the launch, the increase in capacity comes from changes to the tape itself rather than the cartridge format or drive, ensuring that organizations with deployed LTO-10 infrastructure can adopt the higher capacity media without hardware upgrades.

Expanded Environmental Operating Range

Fujifilm has also updated the environmental specifications for the new media to support a wider variety of operational settings. The LTO-10 (40TB) has expanded its recommended operating temperature and humidity range compared to current models such as the LTO-10 (30TB). The temperature range has been extended from 15°C–25°C to 15°C–35°C. The humidity tolerance now supports up to 80% under conditions of 15°C–25°C.

These enhancements enable stable performance even in high-temperature and high-humidity environments. The company states that this makes the media a versatile data storage solution suitable for a wide variety of operational settings. This flexibility addresses the needs of data centers that may operate under varying environmental controls while maintaining reliable data protection standards.

Market Context and Security Implications

The launch adds a second capacity point within the LTO-10 generation, a move that is unusual for the Linear Tape Open standard. Historically, LTO technology advances capacity only when a new drive generation arrives. In this case, Fujifilm is launching the 40TB cartridge as an advanced iteration of the 30TB cartridge instead of a straight-up replacement for it. This approach turns the highest-capacity tier of the LTO-10 generation into a commercially available product earlier than typical generational cycles might suggest.

The release comes amid escalating cyber threats targeting enterprises and organizations worldwide. Safeguarding sensitive business data, customer information and research results has become a top priority across industries. The press release notes that the cartridge enables secure, cost-effective storage of massive data volumes while addressing the growing need for reliable data protection amid escalating cyber threats. As ransomware and other cyberattacks increasingly threaten businesses, the ability to store massive data volumes securely remains a critical component of disaster recovery strategies.

Commercial availability details indicate that the FujiFilm LTO-10 Ultrium 40TB Data Cartridge carries the part number 16978170. The product is listed with 40TB of native capacity and 100TB compressed capacity by distributors. The confirmation that shipping began in January 2026 aligns with the initial announcement made by FUJIFILM Corporation on December 22, 2025. This timeline ensures that the technology is accessible for organizations planning their storage infrastructure for the 2026 fiscal year.

By refining its fine hybrid magnetic particle formulation and adopting a thinner base film made from aramid material, Fujifilm has packed more storage into the same physical footprint. Together, these changes allow the 30% increase in tape length to be packed into the same physical cartridge without compromising durability or reliability. This development underscores the continued evolution of magnetic tape storage as a viable solution for massive data volumes in an era of increasing digital expansion.
