How to find the right Data Cartridges AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Data Cartridges
- LTO generation compatibility
- Check the drive's supported generations. Older LTO drives read two generations back and write one back, while LTO-8 drives read and write only LTO-7 (including LTO-7 Type M) and LTO-9 drives only LTO-8. A cartridge one generation too old or too new simply won't work in the drive.
- Native capacity
- Size backups using native, not compressed, capacity. Compressed figures assume a compression ratio most already-compressed data never reaches.
- WORM vs rewritable
- Buy WORM cartridges only when compliance requires write-once retention. WORM cartridges cannot be reused or erased.
- Library labels
- For autoloaders and libraries, get cartridges with the correct generation barcode labels or a matching label set. Libraries identify and inventory cartridges by barcode.
- Cleaning cartridge
- Use an LTO Ultrium universal cleaning cartridge, and clean only when the drive requests it. Over-cleaning wears the drive heads.
Brands that matter
- Fujifilm: One of the primary LTO tape manufacturers.
- Sony: Has been a primary LTO tape manufacturer alongside Fujifilm.
- IBM: LTO drive and media brand; IBM-labelled media is common for IBM drives and libraries.
- HPE: LTO drive and media brand, widely used with HPE drives.
- Quantum: LTO drive, library and media brand.
What to avoid
- Choosing cartridges by compressed capacity
- Mixing up LTO generations near the LTO-8 compatibility break
- Used or unsealed tapes for primary backups
Questions
Do all brands work in my drive?
Yes, LTO is an open standard, so any brand of the correct generation works in any compliant drive. Generation matters, not the brand on the label.
