<p>Skyrocketing data volumes, intensifying ransomware threats and long-term retention costs are forcing enterprises to re-evaluate where cold data belongs.</p>
<p>HDDs and cloud systems can store massive amounts of data, but they also entail costs, environmental trade-offs, and security trade-offs. For IT and data leaders, the issue is not <a href=”https://www.techtarget.com/searchdatabackup/feature/Why-tape-based-backup-is-making-a-comeback”>if tape is outdated</a>, but whether recent advancements have made it a more practical option for long-term backup and archive usage. Tape remains relevant for enterprise data protection for several reasons.</p>

<h2 class=”section-title”><i class=”icon” data-icon=”1″></i>How tape capacity is growing</h2>
<p>Higher cartridge density remains a clear selling point for tape. Worldwide data generation continues to rise, driven in part by AI workloads. Demandsage <a href=”https://www.demandsage.com/big-data-statistics/” target=”_blank” rel=”noopener”>predicts</a> that worldwide data volumes will reach 221 zettabytes (221 billion TB) by the end of 2026 — a 22.09% increase from the previous year. That’s 402.74 million TB <a href=”https://explodingtopics.com/blog/data-generated-per-day” target=”_blank” rel=”noopener”>generated every day</a>, according to Exploding Topics.</p>
<p>As organizations expand their archive tiers to keep pace with analytics, AI and compliance, storage density becomes even more important. Over the past decade, tape capacity has increased by 400%. The current LTO-10 generation, introduced in 2025, delivers up to 40 TB native cartridges — a 122% boost over LTO-9’s 18 TB capacity released just four years prior — and 100 TB compressed.</p>
<p>The long-term roadmap is another point in favor of tape. LTO Ultrium extends through LTO-14 and aims to double capacity with each generation. By then, tape is expected to have 365 TB native and 913 TB compressed capacity per cartridge. These predictions give organizations some assurance of how the format might scale to plan <a href=”https://www.techtarget.com/searchdatabackup/tip/Long-term-data-backup-options”>long-term backup strategies</a>.</p>

<h2 class=”section-title”><i class=”icon” data-icon=”1″></i>How tape improves cyber resilience</h2>
<p>Tape is already a widely used secure backup technology. Since its inception, tape has provided strong ransomware protection through an <a href=”https://www.techtarget.com/searchdatabackup/definition/What-is-an-air-gap-backup-Strategy-benefits-and-use-cases”>air gap</a> courtesy of offline storage. Vigilance is still key, however. While ransomware can’t reach tape if it’s offline, organizations can still unknowingly write compromised data to tape backups if the threat wasn’t completely neutralized. LTO-3 introduced WORM and LTO-4 added hardware-based encryption to help prevent threat actors from tampering with data.</p>
<p>These capabilities support cyber resilience and can help organizations meet retention and recovery requirements, such as those in the <a href=”https://www.techtarget.com/searchdatabackup/tip/How-the-3-2-1-1-0-backup-rule-reflects-modern-needs”>3-2-1-1-0 rule</a>. Offline and immutable backups are widely recommended and may be required in some regulated environments. However, these capabilities are no longer enough to protect data.</p>
<p>As the computing world moves forward, <a href=”https://www.techtarget.com/searchsecurity/feature/The-history-and-evolution-of-ransomware”>so does ransomware</a>. Tomorrow’s ransomware capabilities will be different from today’s as they try to outpace security measures. One longer-term area of concern is quantum computing.</p>
<p>Quantum computing is no longer theoretical. A <a href=”https://www.mckinsey.com/capabilities/mckinsey-technology/our-insights/mckinsey-quantum-technology-monitor-2026-a-commercial-tipping-point” target=”_blank” rel=”noopener”>report</a> from McKinsey states that over 300 global organizations are working with quantum technology companies to <a href=”https://www.techtarget.com/searchdatacenter/tip/Explore-future-potential-quantum-computing-uses”>solve business challenges</a> and move from quantum pilots to applications. Quantum computing <a href=”https://www.techtarget.com/searchcio/feature/Quantum-computing-in-business-applications-is-coming”>has the potential</a> to solve some problems beyond today’s technology. According to the report, quantum computing could generate up to $2.7 trillion in econ
