LTO-6 is a\u00a0tape\u00a0format from the Linear Tape-Open (LTO) Consortium released in 2012. It was preceded by\u00a0LTO-4\u00a0in 2007 and\u00a0LTO-5\u00a0in 2010. LTO-7, LTO-8, LTO-9 and LTO-10 formats are scheduled, but not yet available.<\/p>\n\n\n\n

According to the Consortium, LTO-6 offers 2.5 terabytes (TB) of native capacity (6.25 TB compressed) capacity, native sustained data transfer rates of up to 160 megabytes per second (MBps) and compressed sustained data transfer rates of up to 400 MBps. The capacity and data transfer rates for LTO-6 assume a 2.5:1\u00a0compression\u00a0ratio.<\/p>\n\n\n\n

There are many intricate parts to even the simplest cloud backup strategies that IT staff should be aware of to fully reap all of the benefits. This 30-page guide will help get you started with cloud backup by identifying key pros vs. cons of cloud backup, types of backup, vendors in the space, and more.<\/p>\n\n\n\n

LTO-6 drives are designed with backwards-compatible read-and-write capability with LTO-5 cartridges, and backward read capabilities with LTO-4 cartridges.<\/p>\n\n\n\n

Previous LTO format specifications<\/strong><\/h2>\n\n\n\n

LTO-1<\/strong>\u00a0was released in 2000. It was the first iteration of the LTO magnetic tape data storage technology that was an\u00a0open\u00a0standard alternative to the formats available at the time.<\/p>\n\n\n\n

LTO-2<\/strong>\u00a0was released in 2002 with a capacity of 200 gigabytes (GB). It doubled the capacity and speed of LTO-1, improving capacity from 100 GB to 200 GB and speed from 20 MBps to 40 MBps.<\/p>\n\n\n\n

LTO-3<\/strong>, released in 2005, offers 400 GB capacity (800 GB compressed). LTO-3 introduced the write once, read many (WORM)<\/strong> feature that writes information to the tape once and prevents it from being erased. LTO-3 has native sustained data transfer rates of up to 245 GB per hour, compressed sustained\u00a0data transfer rates\u00a0of up to 324 GB per hour and a compressed burst transfer rate of 160 megabytes per second (MBps). Both the capacity and data transfer rates for LTO-3 assume a 2:1 compression ratio.<\/p>\n\n\n\n

LTO-4, released in 2007, offers 800 GB capacity (1.6 TB compressed). It was the first LTO tape format to include 256-bit\u00a0Advanced Encryption Standard-Galois Counter Mode drive-level\u00a0encryption.<\/p>\n\n\n\n

The LTO-5 format, first released in 2010, has a capacity of about 3 terabytes with data transfer rates of up to 280 MBps. LTO-5 tape capacity assumes a 2:1 compression ratio; uncompressed capacity\/throughput is 1.5 TB per 140 MBps.<\/p>\n\n\n\n

Upcoming LTO formats and specifications<\/strong><\/h1>\n\n\n\n

The Consortium has said that\u00a0LTO-7,\u00a0LTO-8, LTO-9 and\u00a0LTO-10\u00a0tape formats will eventually become available, but they are not on the market as of July 2015. Here are the projected specifications:<\/p>\n\n\n\n

Have you adopted the current LTO-6 version or are you still using older LTO versions?<\/p><\/blockquote>\n\n\n\n
