LTO-10 tape now comes in two capacities: the standard 30 TB cartridge and a 40 TB cartridge built on aramid base film. The 40 TB cartridge works in every LTO-10 drive already installed, so you get 33% more capacity per tape with no drive replacement.
Update: the 40 TB LTO-10 cartridge is now shipping. Explore SymplyPRO LTO-10 tape drives (desktop, 2U rackmount and tape library models), or see how its price compares in Is the 40TB Cartridge Worth the Cost?
What’s new with 40 TB LTO-10 tape
- 40 TB native per cartridge (up to 100 TB compressed at 2.5:1). Bigger tapes mean fewer slots, shorter backup windows and simpler media rotations.
- Same LTO-10 drives. Your robotics, workflows and handling stay the same.
- Aramid base film. Aramid allows a longer tape in the same Ultrium shell and is far more dimensionally stable. That’s the key to the extra 10 TB.
- 400 MB/s native transfer rate. A full 40 TB cartridge writes in under 28 hours.
- Two media options. Choose the 40 TB aramid cartridge or the standard 30 TB cartridge to balance cost, capacity and operational needs.
| Standard LTO-10 | 40 TB LTO-10 | |
|---|---|---|
| Native capacity | 30 TB | 40 TB |
| Compressed (2.5:1) | 75 TB | 100 TB |
| Base film | Standard | Aramid |
| Works in existing LTO-10 drives | Yes | Yes |
| Time to fill at 400 MB/s | ~21 hours | ~28 hours |
Why aramid base film matters
Real-world storage doesn’t live in a textbook. As recording density rises, the base film’s stability under changing temperature and humidity directly affects tracking and signal quality. INSIC’s 2024 roadmap highlights the growing importance of tape dimensional stability as densities increase. Aramid’s mechanical properties help preserve track geometry across a wider environmental range.
Data centers: even well-run facilities see hot and cold aisle differences and seasonal humidity drift. More stable media supports steadier streaming at scale.
Media and entertainment, on set and near set: in OB trucks, pop-up bays and on-location rooms, conditions are often “good enough” rather than perfect. A more stable base film gives extra operating headroom within spec, ideal for fast project backup and near-set archive.
Who benefits from 40 TB LTO-10 tape
Enterprise and HPC: fewer cartridges per retention set, a smaller library footprint, and lower energy and cooling for the same archive. For a 10 PB archive, moving from 30 TB to 40 TB media cuts the cartridge count from 334 to 250, saving 84 slots. Analysis by Solutions North Consulting found LTO delivers savings of over 90% versus cloud archival and nearly 80% versus HDD arrays over 10 years for multi-petabyte retention.
SMB and branch sites: at 40 TB native, one-tape backups become realistic for many setups. That simplifies air-gap and off-site rotation: label, vault, done.
M&E studios and productions: bigger cartridges speed up vaulting and reduce handling on fast-turn projects. At 400 MB/s you move about 1.4 TB per hour, so ingest and archive fit production schedules instead of dictating them.
LTO roadmap: headroom through LTO-14
Alongside the 40 TB announcement, the LTO Program refreshed its roadmap through LTO-14, with projected capacities up to 913 TB. Treat the roadmap as guidance rather than a guarantee, but it signals a clear growth path for tape over the next decade. Learn more about LTO.
What this means for Symply customers
If you’re planning LTO-10, or already use it, this is a straight upgrade: more capacity, no drive change.
- Simpler scale-out: keep your existing libraries and mix 30 TB and 40 TB cartridges to suit budget, SLAs and site conditions.
- Operational efficiency: fewer cartridges to track and ship, and faster “tape, label, vault” workflows.
- Resilience at scale: aramid’s stability supports reliable streaming where temperature and humidity fluctuate.
Where Symply fits:
- SymplyPRO XTF Thunderbolt / USB4 desktop drives for deskside ingest and on-set, air-gapped archive.
- SymplyPRO SAS and Ethernet (iSCSI) drives, desktop or 2U Gen2 rackmount, for virtualized backup stacks such as Veeam.
- SymplyPRO XTL 40, XTL 80 and MATTERHORN libraries for more slots, partitioning and multi-drive throughput.

Quick FAQ
Is the 40 TB cartridge a new LTO generation?
No. It’s still LTO-10, enabled by aramid base film and existing LTO-10 drive technology, and it works in current LTO-10 drives.
Will it change how I handle media?
No. It’s handled like any LTO-10 cartridge. You may want to tell 30 TB and 40 TB cartridges apart in your barcode scheme or media pools.
Can an LTO-10 drive read older tapes?
No. LTO-10 isn’t backward compatible. See LTO-10 Explained.
