LTO-5

LTO-5 is an upcoming tape format from the Linear Tape Open Consortium. According to the Consortium, LTO -5 capacity will be in the area of 3.2 TB, with data transfer rates up to 360 MBps (in both cases, a 2:1 compression ratio is assumed, uncompressed capacity/throughput is 1.6 TB/180 MBps).

LTO is a magnetic tape data storage technology developed in the late 1990s as an open standards alternative to the formats that were available at the time. LTO-4 was released in 2007 and can hold 1.6 TB (800 GB uncompressed). LTO-4 was the first iteration of LTO tape to include 256-bit AES-GCM drive-level encryption.
