My DVD Disc can Hold More then Your Blu-ray Disc

May 24, 2009 | Data Storage

With all the talk going around with new breakthroughs in optical technology including the news* from down under (Swinburne University of Technology in Australia) about 5D storage which is reported to hold 10 Terabytes, which is about 2,381 single layer DVD recordable or 280 dual sided DVD+R discs.  It turns out it’s those little nano-particles everyone has been talking about recently.

This should be a huge breakthrough that will get all the pesky tape back-up and hard drives out of the picture permanently?

Thus my point: Data storage size and cost per GB (or Terabyte) does not matter any more.  We certainly know that the application for storage is significant (optical for archive, tape for capacity) but time and time again in both business storage and consumer based buying habits the ‘value’ is far beyond the ’storage capacity’.  This is is the the dilemma facing Blu-ray right now.  The perception of value placed on different formats was really blown away with the Apple iPod.  Distribution (and convenience) over storage function.  Really the game changer is the architecture of distribution and retention vs. per storage capability.

This makes sense as most of us do not walk around with data storage appliances strapped to our backs for maximum storage: we choose the most convenient package for our needs.  The brilliance of the iPod is it took relatively small storage, a compression audio format that reduces the size 20x or more (MP3) , a network for distribution (iStore) and a Digital management console  iTunes and created a sensation based around more, not better.

Now we hard core iPod fans would be offended by “not better”  right?   It effectively solves the users problem with discs or other types of storage like analog audio tape (we used to call them cassette tapes   )  in portability and transport.  Although I listened to one person on the radio discussing the days of the “boom box” and the social buzz around one at the time. Now no one gathers around the box listening to the jams: it’s all on-line.

With USB flash storing up to 64GB (or more) it certainly seems a winner in the portable world but what is USB flash?    It’s a connector (USB) which interfaces with a computer or other storage device.  USB is not the technology that makes non-volatile or ” flash” memory the game-changer (and the ability to erase in small sectors).  It’s all about the connection, the interface cable.

Consider the fact that Micro SD is a strong contender for replacing the optical disc.  Consider how it interfaces with computers.  It’s focus is at cell phones, “smart phones” which don’t easily and conveniently interface with USB without an adapter.

I wonder what can be done with nano-particles and flash non-volatile memory.  That is use electricity to change the structure of the particles instead of laser light.  How will that interface?  will the ‘drive’ become obsolete?

Solid state memory does not spin and the media and “drive” are combined.

All it has to do is plug in to the device. Or a real Apple ‘Nano’  =  nano-particles as in a couple of Terabytes of song and video storage.
