LTO Program Technology Provider Companies (TPCs) released LTO-8 Specification

17th of October the LTO Program Technology Provider Companies (TPCs), released the specification for LTO-8 and the new roadmap. The roadmap was extended to LTO Generation 12, with a storage capacity of 480 TB compressed.

  • The LTO-8 has a native capacity of 12 TB and compressed 30 TB, ideal for long term retention of data. The transfer rate is 360 MB/s native and 900 MB/s compressed. One LTO-8 drive can transfer up to 3,2 TB per hour.
  • For the first time since the LTO format was introduced the LTO-8 specification is only backwards compatible with the former generation LTO-7. The new LTO-8 drives cannot read (and write) LTO-6 BaFe and LTO-6 MP media.
  • On the other side the LTO-8 drive is able to initialize LTO-7 media to an increased cartridge capacity of 9 TB native and 22,5 TB compressed instead of 6 TB and 15 TB in a LTO-7 drive. This cartridge is called LTO-8 type M media. This LTO-8 type M cartridge offers a price advantage of 33% per GB/TB compared to a LTO-7 used in a LTO-7 drive.
  • Availability of LTO-8 media: first LTO-8 cartridges should be available coming December.

Note: Compressed capacities for generations 1 – 5 assume 2:1 compression.
Compressed capacities for generations 6 – 10 assume 2.5:1 compression (achieved with larger compresssion history buffer).
