Quick Glance
Key Features
Design
Ultrium Form Factor — HPE LTO-6 media uses Barium Ferrite (BaFe) magnetic tape in the standard Purple Ultrium shell, built for high-duty library use and long-term retention.
Capacity & Throughput
2.5 TB Native, 6.25 TB Compressed — HPE specifies LTO-6 at 2.5 TB native and up to 6.25 TB at the standard 2.5:1 compression assumption. HPE's own spec page lists a media read speed of up to 400 MB/sec.
Compatibility & Data Protection
Drive & Library Support — Part number C7976A is HPE's rewritable LTO-6 cartridge for HPE and compatible LTO-6 drives/libraries. LTO-6 drives read and write LTO-5 and LTO-6 media, and can read (but not write) LTO-4 media. WORM & Encryption — LTO-6 supports WORM media (sold separately) and AES-256 drive-based hardware encryption where implemented by the drive/library.
