HPE LTO-8 Ultrium 30TB RW Data Cartridge Q2078A
Stores up to 30 TB at 2.7 TB per hour with 2.5:1 compression on a single LTO-8 cartridge
- Stores up to 30 TB per cartridge with 2.5:1 compression
- Writes or reads at 2.7 TB/hour for fast backups
- 85% more tracks than LTO-6 reaching 6,656 tracks total
- Cartridge memory chip speeds access and improves media monitoring
- Bit error rate of 1x10^19 exceeds enterprise SATA disk reliability
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.
