HP LTO Ultrium 1 Tape Cartridge

This single HP C7976BW cartridge provides 2.50 TB native capacity and 6.25 TB compressed capacity for LTO Ultrium 1 tape drives. It is designed for organisations that require reliable offline backup and long-term archive storage on standard LTO-1 media.

Packaged as a single unit

The cartridge arrives as one piece of media without additional cables, software licences or cleaning tapes. Its sole function is to supply the raw tape capacity that the drive hardware and backup application manage.

2.50 TB native and 6.25 TB compressed

That space comfortably holds incremental file backups, database dumps or small-system images written at LTO-1 speeds. It runs out when data growth exceeds the native 2.50 TB limit or when workloads demand the higher throughput and density of later LTO generations.

Questions about this item

How often should the LTO Ultrium 1 tape be replaced in a regular backup rotation?

LTO Ultrium 1 media is rated for approximately 200 full passes; replace cartridges when the drive logs excessive read or write errors or after the recommended pass count is reached.

What capacity limit will be reached first during a sustained backup job?

The native capacity limit is 2.50 TB; with typical compression the effective limit rises to 6.25 TB before a second cartridge is required.

How much power does the tape drive consume when writing continuously all day?

Power draw is determined by the tape drive itself, not the cartridge; the media adds no measurable consumption during continuous operation.
