DDS-4 tape cartridge
This DDS-4 cartridge provides 20 GB native or 40 GB compressed capacity for sequential backup and archive tasks. It fits drives that support the DDS-4 format and ships as a single new tape. The 150 m tape length is suited to unattended overnight jobs on compatible libraries or standalone units.
Suitable for DDS-4 libraries
Organisations maintaining existing DDS-4 autoloaders or single-slot drives can use this media for daily incremental or weekly full backups. Sites that have migrated to LTO, disk or cloud targets will not benefit from this format. Buyers needing higher native capacity or faster throughput should evaluate newer tape generations.
Native 20 GB capacity
The decisive specification is the 20 GB native capacity, which doubles to 40 GB with hardware compression. If the backup set exceeds 20 GB uncompressed, multiple cartridges or a different media type will be required.

Questions about this item
What drive format is required to use this DDS-4 20/40GB tape?
This media requires a DDS-4 compatible tape drive that supports 4 mm cartridges with 150 m tape length.
Can this 20/40GB cartridge be read in a DDS-3 drive I already own?

Check the backup software log for a native size near 20 GB or a compressed size approaching 40 GB and confirm the verify pass completes without errors.
