In an age where our digital footprints are growing faster than ever, the question isn’t just how to store our new data universe of information, but how to do it affordably, sustainably, and securely. In this BlogBytes, we’re looking at LTO-10, the latest generation of LTO technology, designed for the era of exponential data.
WHY TAPE, WHY NOW?
Tape is back—not that it ever really left. With the debut of LTO-10, tape storage proves to be an enduring technology for the most pressing data challenges of our time.
Let’s talk numbers. Firstly, demand for tape is accelerating. The LTO industry shipped a record amount of capacity in 2024, with 176.5 exabytes of new media capacity compressed deployed by organizations globally. That represents 15.4% growth over the previous period, and (except for 2021, which was a rebound from the pandemic’s effects) the most significant increase since 2019.
And that trend shows no sign of slowing down!
Analysts[i] forecast that enterprise data under management will surge from 6 zettabytes (ZB) in 2025 to an eye-watering 35 ZB by 2030. That’s more data created and stored in the next five years than in the whole of recorded history. And not all that data needs to be kept on higher-cost, high-energy flash and hard disk drives (HDDs).
This is where tape’s unique combination of strengths shines through. LTO-10 offers a 66% leap in native capacity over its predecessor, LTO-9, with each cartridge storing up to 30 TB of uncompressed data, and up to 75 TB when using a 2.5:1 compression ratio. And it does so with minimal energy consumption and an offline architecture that makes it inherently resilient to cyberattacks, such as ransomware.
As Phil Goodwin, Research VP at IDC, puts it: “Tape continues to deliver some of the best value in data storage, combining low costs with minimal energy use… The many benefits of this technology should not be overlooked as tape advances and organizations reconfigure their data architectures for the modern era.”
WHAT’S UNDER THE HOOD?
LTO-10 isn’t just about more capacity. It’s also a major technological upgrade under the surface.
First, it boosts both linear and track density, thanks in part to a new advanced strontium-doped barium ferrite (BaFe) tape formulation. These improvements mean significantly more data can be stored in the same form factor cartridge. This allows for 15,104 data tracks per tape—up 68.5% from LTO-9. To maintain reliability with these narrower tracks, the high-bandwidth servo system features a low-mass servo. This feature tracks servo bands more effectively, guiding the drive head for more reliable read/write operations, and improving data throughput in less-than-optimal shock and vibration environments.
Second, LTO-10 drives feature a brand-new read/write head design that eliminates the need for cartridge pre-initialization. That’s less time waiting and more time writing. However, this major design leap also means LTO-10 is not backwards-compatible with earlier generations—a calculated trade-off to unlock the next phase of tape evolution.
The format also includes a 32 KB onboard memory chip in each cartridge (known as LTO-Cartridge Memory), which stores metadata and helps speed up file operations. And everything is wrapped in hardened, enterprise-ready encryption, using quantum-safe AES/GCM256 keys that are ready for tomorrow’s cryptographic threats.
BUILT FOR CYBERSECURITY AND SUSTAINABILITY
If digital transformation is accelerating, so too are the threats. LTO-10’s built-in Write Once, Read Many (WORM) functionality means data can be locked down against tampering—an essential safeguard for compliance and long-term recordkeeping. Hardware-based encryption ensures secure data handling at every stage.
Better still, because tape is not connected to the internet when not in use, it provides a crucial “air gap” that defeats conventional malware and ransomware, as well as the command-and-control methods cybercriminals use to disrupt your data. That “air gap” is also a highly effective safeguard against other forms of data loss, from malicious or accidental employees, to tornadoes, fires, and floods.
From a sustainability standpoint, tape has a lower carbon footprint than disk or cloud storage when used for long-term archiving. Fewer spinning disks mean lower power use, less heat generation, and reduced cooling requirements—essential for companies facing both rising energy prices and growing environmental scrutiny.
FUTURE-PROOFING AT SCALE
HDDs will remain ubiquitous, but they’re beginning to hit a ceiling in areal density—the amount of data that can be stored per square inch—which creates challenges in the age of Artificial Intelligence, where every scrap of innocuous information can be used to train models and unlock new insights.
In the AI era, businesses will need access to vast amounts of affordable archive storage; here, LTO technology fits the bill perfectly. Compared to equivalent HDDs, LTO-10 stores 30 TB using just 12 Gb/in² of areal density, compared to over 1,000 Gb/in² for an 18 TB hard disk. That gives tape an enormous runway for future capacity increases and unparalleled storage density.
According to the INSIC tape technology roadmap, this gives LTO tape a unique advantage: the ability to keep expanding for at least another decade. And because LTO is an open standard supported by multiple vendors, customers aren’t locked into a single supplier or ecosystem—a critical factor in long-term planning.
WHERE IS LTO TECHNOLOGY BEING USED?
Tape isn’t just for disaster recovery anymore. A recent TrendFocus report found that while 60% of users still rely on tape for traditional backups, 65% also see it as their go-to solution for long-term data archiving. Other use cases include storing the lowest-cost tier of cloud data, retaining older copies of backup sets to extend recovery points, and serving as the primary location for large AI training datasets that aren’t needed in real-time.
Enterprise software vendors are on board, too. All the major ISVs that supported LTO-9 will support LTO-10 at or near the time of general release. And while the first LTO-10 drives will be Full-Height (FH), Half-Height (HH) models are expected by late 2026.
LTO TECHNOLOGY: THE FUTURE OF STORAGE TODAY
LTO-10 isn’t a step forward for tape—it’s a leap. With massive capacity, built-in quantum-ready encryption, and ultra-low energy demands, it answers some of the most critical questions businesses are asking today: How do we scale data storage without breaking the bank—or exposing ourselves to risk?
In a world increasingly obsessed with instant access and always-on infrastructure, LTO-10 gives smart organizations something more valuable and strategic: the wisdom of a hybrid approach. Fast storage where you need it, and secure, scalable, sustainable tape where you don’t.
If your organization is thinking long-term, tape is not a thing of the past. It’s the future. And you can start using it today.
