Despite Elon Musk's efforts to eradicate DOGE, LTO tape storage has thrived, reaching an all-time high of 176.5 exabytes shipped in 2024, marking the fourth consecutive year of expansion.
In a surprising turn of events, LTO (Linear Tape-Open) tape storage, often perceived as an outdated technology, is experiencing a resurgence in the world of enterprise storage. This revival is particularly notable in the realm of Artificial Intelligence (AI) and Machine Learning (ML), where massive datasets need to be stored and sometimes archived for historical training data or regulatory compliance.
Recent trends show that LTO tape storage is experiencing significant growth in capacity shipped, with a record 176.5 exabytes (EB) shipped in 2024, reflecting a 15.4% increase over the previous year. This growth indicates sustained enterprise interest in tape storage despite the rise of disk and cloud solutions.
Benefits of LTO Tape Storage in the Enterprise Sector
The benefits of LTO tape storage in the enterprise sector, especially related to AI and ML, include high capacity and cost-effectiveness, long-term data retention and reliability, and energy efficiency. Tape offers very large storage capacities at a lower cost per gigabyte compared to disk and cloud storage, making it suitable for archiving large datasets generated by AI/ML workloads.
LTO tape is highly reliable for long-term, offline storage, reducing risks of data corruption or cyberattacks that can affect online storage. Moreover, tape storage consumes less power when idle compared to always-on disk drives, which is advantageous for the massive datasets required in AI/ML workflows.
Comparison with Other Storage Solutions
When compared to disk and cloud storage, LTO tape storage stands out for its unmatched capacity, reliability, and cost-efficiency for cold storage and archiving. While disk storage is gaining popularity for backup and active data workloads due to faster access and enhanced features, enterprises continue to value tape for its scalable, cost-efficient, and energy-saving storage tier for cold data or infrequently accessed datasets.
| Aspect | LTO Tape Storage | Disk Storage | Cloud Storage | |------------------------|----------------------------------------|------------------------------------|--------------------------------------| | Capacity and Cost | Very high capacity, lower $/GB, cost-effective for large scale storage[1][3] | Moderate capacity, costs decreasing but generally higher $/GB over long term[2] | Highly scalable but recurring costs can be high at scale | | Access Speed | Slower random access, better suited for archival and backup | Faster access, supports quick recovery and active data workloads[2] | Fast access, highly available, suitable for active and dynamic workloads | | Energy and Maintenance | Low power when offline, low maintenance | Continuous power consumption, higher maintenance| No on-prem maintenance, but dependent on provider SLAs | | Security and Durability| Highly durable, offline isolation reduces cyber risks[3] | Vulnerable to cyber risks, requires active management | Security depends on cloud provider, risk varies by policy |
A Niche in Modern Storage Architectures
Tape storage fills a significant niche in modern storage architectures, complementing disk, flash, and cloud solutions. Tape storage is being relied upon by enterprises to fuel their implementations of AI and ML technologies. LTO tape technology is an essential piece of the puzzle for those seeking a cost-friendly, sustainable, and secure solution to support modern technology implementation and data growth.
The Linear Tape-Open (LTO) format roadmap currently goes up to 1,440TB per cartridge when extended to LTO-14. The continued growth of LTO is credited to its role in the AI/ML era, where organizations are reconfiguring their storage architectures to keep up with data growth.
Cost-effectiveness measures like Total Cost of Ownership (TCO), longevity, offline security, and high capacity continue to favor tape storage in 2025. The U.S. government claimed to have saved $1M per year by converting 14,000 magnetic tapes to permanent modern digital records in April 2025, framing the conversion as a triumph for modern technology over the perceived outdated magnetic tape.

In summary, LTO tape remains an important enterprise storage medium complementing faster disk and cloud solutions, particularly for scalable, cost-effective long-term storage of AI and machine learning datasets where frequent access is not required. However, modern storage strategies often use a hybrid approach combining tape for archival and disk/cloud for active processing. Despite the age of magnetic tape, it remains highly favorable for long-term, static data archives.
- In the field of AI and ML, the cost-effective and highly capacity-rich nature of LTO tape storage makes it a suitable choice for archiving large datasets generated by these workloads.
- Tape storage, such as LTO, is being relied upon by enterprises to fuel their implementations of AI and ML technologies, demonstrating that technology is not bound by its perceived age but by its utility and functionality in contemporary scenarios.
