LTO-6 - Efficient Data Storage Technology

Data protection is a very important aspect of any organization. It gives you peace of mind to know that your data is safe with a good backup and recovery system. There are many options for backing up your data, including an offsite server or using drives that are separate to store large amounts of data. An LTO 6 is another option that you can use to keep an offline backup of your information that is both cost-efficient and effective.

About LTO

Linear Tape Open (LTO) is a storage technology that uses a single-reel tape that is of high capacity. This technology was developed by International Business Machines (IBM), Hewlett-Packard (HP), and Quantum, who are also involved in the continuous improvement of the product.

The product is promoted by the LTO Program. The LTO Programs has its standards, one of which is the requirement that any vendor who licenses this technology has to pass verification tests for third party compliance. These are tests that are conducted annually. Products which comply with the LTO format have trademarks for verification on the data cartridges and tape drives.

LTO Technology

LTO technology was introduced in the year 2000, and there has been advancement in the technology over the years. The technology began with generation 1 and is currently on the 6th generation. LTO-6 therefore refers to the sixth and current generation of LTO.

Advancement in the LTO technology from generation to generation focused on different aspects. Some of the aspects included the material that was used to create the tape and the methods that were used to digitally encode and compress data.

The density of the data bits found on the tape and the tape's length when it is in the cartridge are also issues that were considered in technology development. The speed of the tape as it moves through the drive is also considered. The WORM capability and encryption of data were added to the technology as it advanced. Also added was partitioning, which supports the linear tape file system (LTFS).


The sixth generation LTO was introduced in the year 2012. It was an improvement of the previous generations with a storage capacity of 2.5 terabytes (TB). The compressed capacity of LTO-6 is a maximum of 6.25 TB. Before LTO-6 was introduced, the compression ratio for data was 2:1, but with generation 6, the compression ratio is 2.5:1. The transfer rate of data for the LTO-6 is 160MBps, while the transfer rate of the compressed data is 400 MBps.

LTO-6 supports the various features that were added to LTO technology as it advanced including partitioning, data encryption, and write-once, read many (WORM). LTO-6 is compatible with LTO-5 and LTO-4. This means LTO-6 is able to read and write LTO-5 cartridges, and is able to read LTO-4 cartridges. LTO technology has been developed so that each generation is able to read and write cartridges from the immediate previous generation and is able to read from the previous two generations.

Advantages of LTO

Since LTO is an open format technology, it has been licensed by many well-known and established organizations involved in storage of data. This has made it possible to have a wide variety of compatible tape drives and cartridges.
