What This Cartridge Is

The HPE LTO-8 Ultrium cartridge stores up to 30 TB of compressed data at 2.5:1 compression. It is built for large-scale, 24x7 backup environments that need high capacity on a single piece of media.

Practical Limits of LTO-8

The format writes or reads at 2.7 TB per hour assuming 2.5:1 compression. Track count rises to 6,656 from 3,584 on LTO-6, and bit density increases by 85% over LTO-7. Unrecoverable error rate is 1x10^19.

The Deciding Specification

Native capacity is 15 TB per cartridge; the 30 TB figure requires 2.5:1 compression. If your data does not compress to that ratio, you will need more cartridges than the marketing number suggests.

Questions about this item

Which capacity should I choose between the 15 TB and 30 TB cartridges?

The 30 TB figure assumes 2.5:1 compression and 6,656 tracks, while the 15 TB LTO-7 baseline uses 3,584 tracks; pick 30 TB if your data compresses well and you need maximum space per cartridge.

What does the 2.7 TB/hour rate mean when the cartridge is in a drive?

It is the compressed write or read throughput at 2.5:1 compression, so actual speed depends on how much your data compresses in practice.

What interface does this cartridge use and what does it limit?

The cartridge works with SATA-attached LTO-8 drives; the SATA link caps the maximum sustained transfer rate the drive can deliver to the host.
