From ComputerWorld: Optical discs like Blu-ray are losing favor, but Sony and Panasonic don't seem to care. The companies have cranked up the storage capacity on optical media to a stunning 3.3TB.
That's a big advance in Sony's optical storage, which is based on technology used in Blu-ray. The 3.3TB disc is targeted at studios, filmmakers, and broadcasters that store large volumes of video, and at large companies that store infrequently modified data.
For example, video streaming companies could hold a large library of films in storage arrays with many optical drives. Instead of using PCs, servers in data centers could then pull out movies from the drives and serve them to users via the cloud.
The jump to 3.3TB is also a big jump from older optical media. The first CDs came out in 1982 with a capacity of 650MB, and DVDs came out in 1996 with a capacity of 4.7GB. Today's Blu-ray media can store up to 100GB of data, and in 2014, Sony and Panasonic said they will ship 300GB media for optical archival systems in data centers.
