Detailed Specifications
HP C7974A - LTO-4 Ultrium 1.6 TB RW Data Cartridge
Overview :
The HP C7974A cartridge is a rewritable LTO-4 Ultrium tape designed for enterprise backup, archiving and disaster-recovery workflows where high capacity and durability matter. It supports a native capacity of 800 GB and up to 1.6 TB with 2:1 compression, enabling fewer media to manage for large datasets. It fits into data-centre or tape-library environments (for example in server rooms, media vaults or remote edge-sites) and integrates with any LTO-4 drive×and is readable by LTO-5 drives×to offer medium-term archive flexibility. The cartridge is engineered with metal-particle media, supports up to one million passes on any area of tape, and conforms to the LTO standard ecosystem so it can work with HPE and third-party LTO-4 compatible drives.
It is an engineer-oriented storage medium chosen when deterministic long-term retention, low-operational overhead and open-format interoperability are required.
Key Features :
Native capacity of 800 GB and compressed 1.6 TB
Metal-particle recording media with 343 kbits/inch density
Support for 896 data tracks for full LTO-4 format
Durable media over 1,000,000 passes on any tape area
30-year archival shelf life under recommended conditions
