Compact disks to make a comeback?

WOO HOO finally I can do a backup of my entire home network on a single disk!!!! :laugh: :laugh: :laugh: :laugh: :laugh: :laugh:

Researchers demonstrate 3D nanoscale optical disk memory with petabit capacity[^] Yes, you heard that right: petabit - 100+ terabyte CDs. High density, low power, long life. And this is a prototype - so expect production to be closer to petabyte if it ever gets there. :omg:

That should be enough to backup all my personal data, my photos in the cloud and my precious ('ahem') multi-arcade machine research data... :laugh:

I did that in the late 1980s, when I got my first CD burner! (My entire home network consisted of a single PC in those days, but that was the normal situation.)

I wouldn't dare try these days :-) My NAS on it's own would toast a couple of cases of media. It holds about 12tb of storage, if which about 8 is used. Then there's the server with about 50 ish 30th BUs running ..... Scares me just thinking about it.

If you have a CD/DVD damaged by ionizing radiation, you have much bigger problems than data loss... :) Electronic storage (RAM), magnetic media (HDDs) or electron traps (SSDs) can definitely be affected by radiation, changing single bits in the memory. When dealing with physical pits (as in manufactured CD-ROMs/DVDs etc.) or chemical changes (as in CD-R/DVD-R etc.) on a larger scale - it's less likely.

It's estimated that ignoring physical data (books, papers, ...) we as a planet currently store over 60 zettabytes (1 billion terabytes), and that 90% of that data was created in the last two years. And apparently, the volume of data in the world doubles in size every two years. Back in 2008, Google alone was processing 20 petabytes a day. Throw in Farcebok, tiktok, twatter, and the cloud and gawd know how much is processed today. The important thing to remember is that data expands to fill available space (plus 10%) :laugh:

What a waste of hardware.
I must admit that I contribute to that myself. Just like I like to go to my bookshelf just looking at their backs, reading their titles and recalling the story (sometimes I pick the book from the shelf to re-read a chapter or passage) - I used to go to the library find good books but hated returning them - in a similar way, it gives me a good feeling to know that my favorite movies are available in my shelves. All my favorite music as well. Just seeing a CD cover can lighten my mood. No streaming service bankruptcy can take away my access to books, music or movies. No censorship, no economic decision cleaning out the space to make room for more profitable pieces. And: It is nobody's business which books I read, at which times and how many times I re-read which parts of the book. Or watch a movie. Or listen to a piece of music. I've got several terabytes of electronic information, several terabytes of printed information, practically all of it redundant. It could have been retrieved from elsewhere. But I want to have it available, here at my fingertips.

Presumably you mean that printed material is stored electronically rather than physically. Following estimates that a terabyte would hold 1 million books. Probably not realistic to idly scan that number. How many e-books can you put on a 1 TB hard drive? - Quora[^]
