Sony increases optical disk storage to 3.3TB


Optical discs like Blu-ray are falling out of favor, but Sony and Panasonic don’t seem to care. Companies have increased storage capacity on optical media to 3.3TB.

It’s a big step forward in Sony’s optical storage, which is based on the technology used in Blu-ray. The 3.3TB drive is intended for studios, filmmakers, and broadcasters that store large volumes of video, and large businesses that store data that is rarely changed.

For example, video streaming companies might hold a large library of movies in storage arrays with many optical drives. Instead of using PCs, servers in data centers could then extract movies from disks and serve them to users via the cloud.

The jump to 3.3TB is also a big leap from older optical media. The first CDs were released in 1982 with a capacity of 650 MB, and DVDs were released in 1996 with a capacity of 4.7 GB. Today’s Blu-ray media can store up to 100 GB of data, and earlier this year, Sony and Panasonic announced that they will ship 300 GB media for optical archiving systems in data centers.

Optical storage keeps pace with SSDs and hard drives in the race to cram more storage into drives and media. But unlike magnetic drives or NAND flash memory, optical storage is not designed for regular reads and writes, which limits its use.

However, the medium remains for this form of optical storage due to the reliability. Sony claims the media will have a lifespan of 100 years, longer than other storage technologies.

It remains to be seen whether the new development would result in an increase in the capacity of Blu-ray discs. Current capacity is considered adequate for 4K movies.

The 3.3TB media is part of Sony’s second generation optical disc archiving system, a successor to the original system launched in 2013. Sony has also announced optical drives to support the new media. Newer drives are faster than predecessors and generic Blu-ray players, which have noticeably slow read and write times.

Optical drives will be available as a USB drive unit that plugs into a computer’s USB port, a Fiber Channel library drive unit for storage systems, and an archive cartridge. optical drive for data centers. The discs will ship this summer, Sony said.

The new media will work with Everspan, Sony’s robotic storage system that can store up to 181 petabytes of data. Sony offers Everspan as an alternative to tape or hard drive storage in data centers.

Sony encourages companies to support the Optical Disc Archive system, which is being touted as a new system for storing archived data. Sony said 42 companies have created interfaces for storage technology.

The 3.3TB media and drives were announced at the NAB Show in Las Vegas, where Sony is also previewing several products related to 4K video.
