Tape has been called “dead” for decades. Yet some of the largest data operations in the world still write petabytes to tape every year. If anything, tape matters more now than it did ten years ago.
This guide explains who still uses tape storage, why they rely on it, and what it means for your own backup and archive plans. As a company that buys and processes used LTO and IBM 3592 tapes every day, we see firsthand how much tape is still in active use.
Quick answer: Tape storage is still widely used by cloud providers, banks and financial firms, government and research labs, healthcare systems, and media companies. They use LTO and IBM 3592 tape for long-term archives, compliance retention, and offline “air-gapped” backups because tape offers the lowest cost per terabyte, decades-long shelf life, near-zero power use at rest, and strong protection against ransomware.
Is Tape Storage Still Used?
Yes. Tape is still a core part of enterprise storage. The newest generation, LTO-10, launched in 2025 with cartridges holding 30TB or 40TB of native data, according to the LTO Program. IBM’s 3592 line offers cartridges up to 50TB native.
Tape is rarely used for daily work. Instead, it holds the data that must be kept for years, rarely read, and never lost.
Who Still Uses Tape Storage?
Cloud and Hyperscale Providers
Large cloud and internet companies store huge amounts of “cold” data that customers rarely access. Tape is widely used behind the scenes for this kind of deep archive storage because it is so cheap per terabyte at scale.
A well-known example: in 2011, Google restored Gmail accounts affected by a software bug from tape backups. It was a public reminder that even the biggest tech companies keep offline copies.
Banks and Financial Services
Financial firms must keep transaction records, communications, and audit data for years under regulatory rules. Tape provides affordable long-term retention and a physical, offline copy that ransomware cannot reach.
Government and Research Labs
Government agencies and research organizations hold some of the largest data archives on earth. CERN, for example, stores its physics research data in a large tape archive. Weather, space, and national archive data also rely on tape for long-term preservation.
Healthcare
Hospitals and health systems retain imaging and patient records for long periods. Tape is a common choice for archive copies and disaster recovery.
Media and Entertainment
Studios and broadcasters create massive video files, and high-resolution footage multiplies storage needs fast. Tape is a standard way to archive finished projects and raw footage at a manageable cost.
Why Tape Still Wins
If you want the technical background, see our guide on how data is stored on tape. Here is why organizations keep choosing it:
- Lowest cost per terabyte for long-term storage
- Air gap protection: A tape on a shelf is offline and cannot be encrypted by ransomware
- Long shelf life: Tape can retain data for 30 years or more when stored properly
- Low power: Tape uses no electricity while sitting in a slot or on a shelf
- WORM options: Write-once cartridges help meet compliance rules
- Built-in encryption: Modern LTO drives support hardware encryption
The Risks of Skipping Tape
Organizations that go all-disk or all-cloud for long-term retention can run into:
- Rising costs from paying monthly for data that is almost never accessed
- Ransomware exposure when every copy is online and reachable
- Compliance gaps where regulators expect immutable or offline records
- Lock-in, with expensive fees to move large archives out of a provider
Most mature teams use a mix: disk for fast recovery, cloud for flexibility, and tape for the long-term, offline copy.
What It Means for Your Organization
Here is what we recommend to IT leaders reviewing their tape strategy:
- Audit your tape inventory. Know which generations you have, how many, and what is on them.
- Plan your next generation. LTO-10 drives cannot read older LTO cartridges, so plan migrations carefully. If you run IBM 3592, check your drive roadmap too.
- Keep at least one offline copy of critical data.
- Sanitize retired tapes to NIST 800-88 standards before they leave your control.
- Sell surplus media instead of storing or shredding it.
Upgrading? Your Old Tapes Have Value
Every tape migration leaves behind cartridges you no longer need. Many still have resale value, especially recent generations and new or lightly used stock.
When you sell your used tape media to We Buy Used IT Equipment, we quote your tapes against current market demand, arrange secure shipping, and erase every cartridge through our Phoenix Certified Process. You receive a certificate of data destruction and payment once your tapes are processed.
Final Thoughts
Tape is not a relic. It is a quiet workhorse behind cloud archives, bank records, research data, and media libraries. Low cost, long life, and a real air gap keep it in demand.

Frequently Asked Questions
Is tape storage still used in 2026?
Yes. Tape is widely used for long-term archives, compliance retention, and offline backups. LTO-10 launched in 2025 with 30TB and 40TB native cartridges, and IBM 3592 cartridges reach up to 50TB native.
Why do companies still use tape instead of the cloud?
Tape offers the lowest cost per terabyte for data that is rarely accessed, uses no power at rest, lasts for decades, and can be stored offline where ransomware cannot reach it. Many companies use tape alongside cloud and disk.
How does tape protect against ransomware?
A tape that is removed from the drive and stored on a shelf or in a vault is offline. Ransomware cannot encrypt or delete data it cannot reach, so tape gives you a clean copy to restore from.
Can I sell my old LTO tapes?
Yes. Many used LTO and IBM 3592 tapes have resale value. We Buy Used IT Equipment buys used tape media, erases every cartridge to NIST 800-88 standards, and provides a certificate of data destruction.
Can LTO-10 drives read older LTO tapes?
No. According to the LTO Program, LTO-10 drives do not support reading or writing earlier LTO generations. Keep a compatible drive available, or migrate older data, before retiring your previous drives.
