FUJIFILM LTO Ultrium 6 WORM 2.5 TB Data Cartridge (LTO FB UL-6WORM 2.5T J)
FUJIFILM LTO Ultrium 6 WORM removable data cartridge. This record covers the media model only; the drive, host interface, software, and recording workflow are separate equipment.
MEDIA ONLY: FUJIFILM LTO Ultrium 6 WORM 2.5 TB Data Cartridge (LTO FB UL-6WORM 2.5T J). This is write-once/read-many media: after a successful write, recorded data cannot be overwritten or erased through normal LTO operation. Use it only with a WORM-capable drive and backup application. Host connectivity belongs to the drive, not the cartridge.
Capacity, generation, interface and compatibility
| Manufacturer model | LTO FB UL-6WORM 2.5T J |
|---|---|
| Format / generation | LTO Ultrium 6, half-inch magnetic tape cartridge; WORM media. |
| Native capacity | 2.5 TB. Compressed-capacity estimates are workload- and software-dependent and are not guaranteed storage capacity. |
| Interface | The cartridge has no electrical host connector. An LTO drive provides the host interface (commonly SAS or Fibre Channel, varying by drive model); confirm the drive, HBA, cable, firmware, and system support as a matched chain. |
| Drive compatibility | FUJIFILM lists this generation for read/write use in LTO-6 and LTO-7 drives. WORM operation additionally requires explicit WORM support in the drive and backup software. Do not infer compatibility from the cartridge shell or generation number alone. |
| Write mode / handling | This is write-once/read-many media: after a successful write, recorded data cannot be overwritten or erased through normal LTO operation. Use it only with a WORM-capable drive and backup application. Keep the cartridge in its case, label the model and generation, avoid touching tape or drive-contact areas, and follow the selected drive's acclimation, cleaning, and environmental guidance. |
Identification and preservation
LTO Ultrium generation 6; WORM magnetic tape cartridge, with 2.5 TB native capacity and exact Fujifilm model designation LTO FB UL-6WORM 2.5T J. The exact model string is included because capacity and read/write behavior depend on both the tape generation and whether the medium is WORM. Check the cartridge label and its internal memory information through a supported drive; retain the original packaging and acquisition details where available.
- Use the manufacturer's media/drive compatibility matrix and the drive manual rather than assuming cross-generation support. A drive may read or write older generations differently, and this listing does not promise interchange across vendors or firmware revisions.
- Keep valuable data in multiple independent copies, verify checksums and restores, and plan migration before compatible drives or service parts become unavailable.
