LTO-9 20-cartridge pack

This pack contains twenty Quantum LTO-Ultrium 9 data cartridges, each providing 18 TB of native capacity and up to 45 TB when compressed. The media uses Barium Ferrite technology and supports a native transfer speed of 400 MB/s. It is designed for small and medium businesses that need high-density, offline backup for large databases and archives.

Suits SMB archives; not for random access

Organisations that write sequential backups to a compatible LTO-9 drive and store cartridges offline will benefit from the low cost per terabyte and long shelf life. Environments that require frequent random reads, low-latency access, or direct-attached disk performance should consider a different storage tier.

Capacity per cartridge decides fit

Each cartridge delivers 18 TB native and 45 TB compressed capacity, so the total raw space scales directly with the number of cartridges purchased. The 3395.67 ft tape length and simplified tape path support reliable streaming writes, but the single figure that determines whether this pack meets the requirement is the per-cartridge native capacity.

Questions about this item

Should I buy the 20-pack or look for single cartridges?

This item is sold as a 20-pack of LTO-9 cartridges. Each cartridge provides 18 TB native capacity and up to 45 TB compressed, so the pack delivers 20 times those individual figures.

What does the 400 MB/s native transfer speed mean when the tape is in my drive?

The 400 MB/s native rate is the sustained write or read speed the LTO-9 drive can achieve with this media under typical conditions. Compressed data can move faster, limited by the drive's compression engine and host interface.

Does the LTO-9 interface cap the 45 TB compressed capacity in practice?

The LTO-9 format defines 18 TB native and 45 TB compressed per cartridge. Realised capacity depends on data compressibility; highly compressible datasets approach 45 TB while already-compressed files stay near 18 TB.
