The September 24 will be marked as a historic day in consumer data storage technology history. Hitachi has unveiled a method of storing digital information on slivers of quartz glass that can endure extreme temperatures and hostile conditions without degrading, almost forever. [i]“The volume of data being created every day is exploding, but in terms of keeping it for later generations, we haven’t necessarily improved since the days we inscribed things on stones,”[/i] Hitachi researcher Kazuyoshi Torii said. [i]“The possibility of losing information may actually have increased,”[/i] he said, noting the life of digital media currently available — CDs and hard drives — is limited to a few decades or a century at most. And the rapid development of technologies has resulted in frequent changes of data-reading hardware. [i]“As you must have experienced, there is the problem that you cannot retrieve information and data you managed to collect,”[/i] said Torii, apparently referring to now-obsolete record players and cine films. Hitachi’s new technology stores data in binary form by creating dots inside a thin sheet of quartz glass, which can be read with an ordinary optical microscope. Provided a computer with the know-how to understand that binary is available — simple enough to program, no matter how advanced computers become — the data will always be readable, Torii said. The prototype storage device is two centimetres (0.8 inches) square and just two millimetres (0.08 inches) thick and made from quartz glass, a highly stable and resilient material, used to make beakers and other instruments for laboratory use. The chip, which is resistant to many chemicals and unaffected by radio waves, can be exposed directly to high temperature flames and heated to 1,000 degrees Celsius (1,832 Fahrenheit) for at least two hours without being damaged. It is also waterproof, meaning it could survive natural calamities, such as fires and tsunami. [i]“We believe data will survive unless this hard glass is broken,”[/i] said senior researcher Takao Watanabe. The material currently has four layers of dots, which can hold 40 megabytes per square inch, approximately the density on a music CD, researchers said, adding they believe adding more layers should not be a problem. Hitachi have not decided when to put the chip to practical use but researchers said they could start with storage services for government agencies, museums and religious organizations.[/quote] [url=http://www.pc-tablet.com/6655-hitachi-glass-silvers-technology-stores-data/]Source[/url] [url=http://www.japantoday.com/category/technology/view/glass-slivers-that-store-data-forever-unveiled-by-hitachi]Another source[/url]
but we can't delete our bestiality and cp? what if the police find our glass
this seems like just high-tech stone writing to me or did I read it wrong
[QUOTE=a-cookie;37796362]but we can't delete our bestiality and cp? what if the police find our glass[/QUOTE] You know police can easily recover data if they take your modern normal hard drives, right? Files don't go away with a simple shift delete.
Fancy. Now watch as this too disappears and is never heard again. [QUOTE=Robbi;37796387]You know police can easily recover data if they take your modern normal hard drives, right? Files don't go away with a simple shift delete.[/QUOTE] Like any sane person wouldn't use either a 35-sweep deletion (minimum) or a magnet.
This isn't meant for consumer use, don't act surprised if you never hear of it again.
Hitachi? Making durable storage peripherals? My pile of dead Travelstars would like to have a word with them.
[QUOTE=Robbi;37796387]You know police can easily recover data if they take your modern normal hard drives, right? Files don't go away with a simple shift delete.[/QUOTE] I remember reading somewhere that recovering files after a zero-fill is exceedingly difficult. there's something like a 50% chance to recover a single bit accurately
[QUOTE=Robbi;37796387]You know police can easily recover data if they take your modern normal hard drives, right? Files don't go away with a simple shift delete.[/QUOTE] If you're storing illegal things, you're probably smart enough to know how to properly erase things
Yet Hitachi can't make a decent hard drive for the life of them. There are so many dead Hitachi drives that I have from older fixes. [b]SO MANY[/b]
I was gunna post this but there was so much jargon i got lost simply copy/pasting. THRILLING news nonetheless
[QUOTE=The golden;37796430]That's why you use a file-shredding program if you're trying to removal personal or business documents.[/QUOTE] It's still possible to restore, although you have to go through a lengthy process. Safest option is probably to physically destroy it, i think. :v:
there's also a really neat article showing the advances in technology over the decades, check it out!
[QUOTE=Robbi;37796387]You know police can easily recover data if they take your modern normal hard drives, right? Files don't go away with a simple shift delete.[/QUOTE] Zero the files.

Safest option is probably to physically destroy it, i think. :v:[/QUOTE] It costs a fortune to restore data that's been wiped with a single pass. The military calls 7 passes good enough as I recall. It's not anywhere as close to as easy as you seem to think.
Reminds me of the glass looking memory chips from Minority Report.
[QUOTE=Robbi;37796387]You know police can easily recover data if they take your modern normal hard drives, right? Files don't go away with a simple shift delete.[/QUOTE] A 2 pass format is almost always more than enough for modern HDD's.

[QUOTE=imadaman;37796389] Like any sane person wouldn't use either a 35-sweep deletion (minimum) or a magnet.[/QUOTE] nobody has access to a magnet strong enough to do anything to a hard drive
[QUOTE=Dori;37797194]nobody has access to a magnet strong enough to do anything to a hard drive[/QUOTE] What about one of those magnets used to move cars around? I would think that could do some damage. I never really understood how you can recover a file if the bits the file was stored in were all set to zero. I mean what, do you look for leftover magnetic signatures?
[QUOTE=DaMastez;37797306]What about one of those magnets used to move cars around? I would think that could do some damage. [/QUOTE] when I say nobody I mean no average person [editline]1[/editline] and afaik not even that kind of magnet is strong enough

I can assume it'd last for more than a century, but I wonder just how long it could actually last. A few centuries, a millennium? Just how long could said Glass Silvers actually last? Being that glass is essentially a liquid, i'd imagine it'd degrade over the centuries, but this hard glass sounds more durable so long as it doesn't get cracked.
So in the future, grandma's chandelier will also store her dinner roll recipes?

[QUOTE=Dori;37797845]accidentally having cached thumbnails of child porn in your hdd is not a convictable crime[/QUOTE] The FBI would disagree with you. People absolutely lose their minds whenever anyone mentions pedophilia. Even the accusation of it is enough to potentially ruin someones career.
