  • Highest Capacity and Performance of any Comparable Tape Technology
  • HPE LTO-6 Ultrium can write or read data at a blistering 1.4 TB/hour, storing, encrypting and protecting up to 3 TB on a single cartridge, making it the big hitter in large-scale, 24x7, mission-critical IT environments.
  • A 70% increase in the number of tracks has increase the bit density, allowing more data to be recorded in the same amount of tape: from 1,280 tracks for LTO-5 to 2,176 tracks for 6th generation HPE LTO-6 Ultrium 6.25 TB cartridges.
  • LTO Ultrium cartridge memory chip delivers faster access time and enhanced media monitoring.
  • First time restore ensured with fewer media failures and disrupted backups, regardless of duty cycle or environmental conditions.
  • Ultra-reliable
  • Superior 'smart grabber' mechanism and mechanical interlock to prevent the leader pin from being pulled inside the tape housing. Sensors detect proper connection and prevent leader loss that would ruin the tape.
  • Simplified tape path to reduce wear and tear and build up of and debris (important in automation).
  • HPE brand qualification test procedures (load/unload, shoeshine, drop testing and environmental stress testing) go far beyond what is required for the LTO Ultrium logo. This ensures maximum reliability for restoring your data.
  • HPE warrants LTO Ultrium cartridges for up to 30 years archival life. This ensures businesses can meet the ever-increasing demands of regulation for data retention and archiving.
  • Secure
  • Write-Once-Read-Many (WORM) version provides tamperproof, compliant data storage.
  • Data encryption for enhanced data security on HP LTO-4, LTO-5 and LTO-6 Ultrium. Compliance with FIPS 140-2 level 1 security standards.
  • Value for money
  • Standardizing on HPE LTO-5 or LTO-6 Ultrium delivers the capacity to meet shrinking backup windows, industry-standard, AES 256-bit encryption (IEEE1619.1), and interchangeable RW or WORM media; without extra space or IT resource overhead.
  • Open standard technology ensures compatibility across product generations and gives you more choice. Cartridges are available as Custom Labeled, Non-Custom Labeled (both Custom and Non Custom include RFID options from LTO-4 onwards) and non-labeled versions.
