Linear Tape-Open (LTO) is a magnetic tape data storage technology, which was originally developed in the late 1990s as an alternative to the proprietary magnetic tape formats available at the time, based on open standards. This article presents the different LTO-generations.
LTO generations
| drive generation | band generation | capacity | |
|---|---|---|---|
| Native | HW-compressed[1] | ||
| Ultrium 1 | LTO-1 | 100 GB | 200 GB |
| Ultrium 2 | LTO-2 | 200 GB | 400 GB |
| Ultrium 3 | LTO-3 | 400 GB | 800 GB |
| Ultrium 4 | LTO-4 | 800 GB | 1,6 TB |
| Ultrium 5 | LTO-5 | 1,5 TB | 3,0 TB |
| Ultrium 6 | LTO-6 | 2,5 TB | 6,25 TB |
| Ultrium 7 | LTO-7 | 6 TB | 15 TB |
| Ultrium 8 | LTO-7 (M8) | 9 TB | 22,5 TB |
| LTO-8 | 12 TB | 30 TB | |
| Ultrium 9 | LTO-9[2] | 18 TB | 45 TB |
LTO hardware compression
Ultrium drives provide a hardware compression function. The compression rate is dependent on the kind of data. Data that has already been compressed like JPG- or ZIP-file can hardly be compressed any further. Other uncompressed data are compressed to a correspondingly higher degree.[3]
The hardware compression can be configured in the backup program used in each case. Information can be found for example in the SEP-software Wiki.[4]
