For storage teams managing data that must survive for years, LTO Ultrium remains the quiet workhorse behind the world's most resilient archives.
LTO density roughly doubles every generation. Grow your archive by adding cartridges to a shelf — not arrays to a rack. LTO-9 holds 18 TB native; LTO-10 jumps to 30 TB.
A removed cartridge cannot be reached over the network. Pair that physical air-gap with hardware AES-256 encryption and write-once WORM media for true data immutability.
Idle tape draws no power. With the lowest cost per terabyte in storage and near-zero energy at rest, LTO keeps both your budget and carbon footprint down.
The published LTO roadmap extends through Generation 14. Native capacities shown; compressed is typically 2.5×.
