Tape media and drive companies have begun shipping the sixth generation of linear-tape open (LTO) technology, which like previous generation upgrades, significantly increases the capacity and data throughput capabilities for backup and archive applications.

LTO-6 cartridges can hold up to 2.5TB natively or 6.25TB of compressed data. Compared with previous generation LTO-5 drives and cartridges, the new LTO-6 cartridges more than double capacity (with compression) and offer a 40% performance boost. LTO-5 held up to 1.5TB natively and 3TB of compressed data. The LTO-5 drives had a native data transfer rate of 200MBps or up to 1TB per hour with 2:1 compression. LTO-6 tapes also include encryption and WORM (write-once, read many) capabilities that were also offered with the past two generations of LTO tape drives and media.

LTO-6 drives will provide backward compatibility with the ability to read and write LTO-5 cartridges and read LTO-4 generation cartridges.

128TB tape cartridges key to kilometer-size telescope

In one day, the telescope's dishes will generate 10 times the network traffic produced at the same time on the global Internet. They will feed about 10 petabits of data (1 billion gigabits) per second into a central computer that will have the processing power of about 100 million of today's PCs.  The project plans to generate 1 million GB of data per day and store 300 to 1,500 petabytes (1.5 exabytes) of data per year. IBM is responsible for the data storage and they plan to use tape. "The tape will be used as a deep archive." Construction is expected to start in 2016 and take four years. The exascale supercomputer is expected to be completed by 2024.
