Overview

The HP LTO-6 Ultrium C7976A Data Cartridge five-pack provides a straightforward, proven solution for enterprise backup and archival workflows. Each cartridge delivers 2.5TB of native storage capacity, expanding to 6.25TB with hardware-level compression, and supports write speeds of up to 350MB/s. For organizations already invested in LTO-6 tape infrastructure, this bundle offers a cost-effective way to keep backup media stocked without overspending on individual purchases.

Built to the LTO Ultrium Generation 6 standard, these cartridges benefit from the format's well-established reliability and cross-vendor compatibility. They work seamlessly with LTO-6 drives from HP and other manufacturers, and maintain backward compatibility with LTO-5 systems for read/write operations. Whether used for nightly incremental backups, disaster recovery sets, or cold archival storage, the five-pack format makes it easy to maintain a rotation schedule and keep critical data protected on proven, offline media.
