Is LTO still the best option for archiving?

LTO tape remains one of the most reliable and cost-effective options for long-term data archiving. The latest generation, LTO-10, offers up to 30TB of native capacity, with future versions projected to handle hundreds of terabytes per cartridge. It provides a very low cost per terabyte, a lifespan of 30 years or more when stored properly, and strong protection against ransomware due to its offline nature. These qualities make it well suited for organizations that need to store large volumes of data securely for long periods.

Cloud and disk storage have their own advantages, particularly for quick access, global scalability, and advanced search features. However, they often carry higher long-term costs and less inherent security compared to tape. LTO requires more effort in terms of handling and maintaining hardware, but it offers greater durability and lower overall costs for seldom-accessed archives.

For businesses, media companies, and institutions that must preserve critical archives, LTO continues to be the most practical solution in 2025. Cloud services are a better choice when frequent access and collaboration are priorities, while a combination of both can provide a balance between cost, security, and accessibility.
