Years and years of cloud talk has most of us thinking that physical media (other than servers) is dead. Not so, says Sony and Panasonic. Behold, the Archival Disk, which will eventually be able to store a terabyte of information, as opposed to the paltry 50 gigs that Blu-ray offers. It even has its own logo already.

But, judging just by its name alone, it doesn’t seem to be the usual strategy of making us buy our media library all over again (like the consumer-aimed “Blu-ray”). No, this is a business storage media.

An article on BBC News addresses this seeming paradox:

In an era of digital and cloud storage, some have questioned the point of such discs but actually such systems are crucial, thinks Gartner analyst Paul O’Donovan.

“If you want to hand on your photos to your grandchildren we are going to need somewhere to store it all,” he said.

“Cloud servers have to store massive amounts of data and have to be able to hold on to it for a long time.”

Panasonic and Sony were also keen to talk up the benefits of physical discs.

“Optical discs have excellent properties to protect themselves against the environment, such as dust-resistance and water-resistance, and can also withstand changes in temperature and humidity when stored,” the firms said in a statement.

The article even goes on to mention that Facebook is testing a system of 10,000 Blu-ray discs in a special storage cabinet as a backup for all its users’ media.

It’s almost like all the financial wizards telling you to buy gold when they’re really stockpiling silver.

Or, it’s just a failsafe. We back up our physical media to the cloud, which is then backed up to physical media. That data has to reside somewhere, after all. But who is saving the savers?
