It seems some scientists are making that claim with this new discovery. They claim that this can erase the need for hard drives and any other storage form with this layer of protien fibers, capable of storing 50 terabytes (50,000 gigs) of data. Right now I'm skeptical.. but what do you think? The future of computing and data storage using organic protiens?

I would rather have such a thing as a hard drive rather than a disk, but that's quite impressive. But they say it sustained for a few years... I'd like my stuff to store a bit longer than a few years...

I hope it's right though, because I could use 50 terrebites on my laptop. Then I'll be set for storing things for the next 15 years.

its mostly speculation right now, I think Bluray will still make a big hit for a few years minimum.

cool stuff though, if hes that good with the stuff he could probably make a HDD like device to store data onto.

I would imagine that they could use a reader such as a CD drive without the opening and closing function and have that work just as well as a hard drive. The only things I see that the hard drive has over this is that hard drives have a faster read speed and they don't naturally decay over time.. though things may change.

I read something the other day that said most CD and DVD media we write to at home only actually lasts a couple of years. Thats even if you don't use it and store it in decent conditions.

Cheers

A couple of years = 2 years. I really don't think that is true.

one thing, buy a good brand of CDR's I bought some cheap stuff and put some backup on them, and stored them in a normal case about a year later I was going through it to see if there was anything useful on it I had forgot about, took it out of the case and rubbed my finger across the top surface(not shiny) and voila a nice big hunk of that reflective plastic came off


anyway back on topic
even if they do succeed in making these, if the write speed is how it is now then it will be much too slow to replace hdd but how it looks, I bet it would be faster
thing I want to see is one of those disks except extremely small(probably at least 1gb still) like small enough to fit into a cellphone or say a digital camera(replacing sandisks as well!)

i also did that once. i had a cd where i had loads of small games and utilities (freeware stuff ofcourse). i have had that disk since 2001, and in 2005 i was going to see what fun i had put on it, but then the reflective plastic came off when i touched it.

that was quite fun because i could draw stuff on it by lightly rubbing my finger nail to it


I do wonder what the games manufacturers use for they CD's.
my copy of Thief: The Dark Project, which i bought in 1999 is still as good as new. not a single scratch on it, because i love that game and try to keep it as fresh as possible.

Those are not re-writable though. You could cover them with transparent plastic. I guess that re-writable do only last about 2 years then.

i dont like the sound of seemingly infinately big storage devices:
1) it'd give me an excuse to ntot delete stuff and keep my files organised
2) when looking for a file, wouldn;t it take your pc ages to find the files location on the disk?

"HiSpace (www.hispace.com) have recently launched a new range of CD-Rs aimed at digital photographers. These disks use 24 caret gold to help add stability to the disks. As a result, they come with a 100 year warranty."

That is the exception, not the rule, however.

"Many of the cheap burnable CDs available at discount stores have a life span of around two years," Gerecke says. "Some of the better-quality discs offer a longer life span, of a maximum of five years."

Which seems to be the norm. Pressed CDs (i.e. bought ones) last longer, but ones you burn yourself aren't going to last longer than a can of tuna.

Just like they said 640K of RAM was more than you'd ever need (quoted from Bill Gates), and 1.44MB floppy disks were the solution to everything when we had 720K disks. Then the 10 Megabyte hard drive came along and that could store your operating system and all the files you'd ever own.

We'll always outgrow whatever they sell us.

Quote: "A couple of years = 2 years"
Definition of couple is 2, but can also be applied to a few items. Think the dictionary defines it as the informal version or somesuch. Essentially when being precise (eg. man and wife) then it is 2, but when less precise then means few. eg. I'll be a couple of days doesn't translate normally to exactly 2 days. It's sort of "don't know exactly, but more than one, and probably less than five".

Quote: "I really don't think that is true"
Well it was either in a PC mag I was reading or one of those gadget blogs (that links to companies), and it said that they found this was the case in most cases. I know for a fact that some of my older CD-Rs (say about 5-10 years old) have problems accessing the data. Heh, when I was having a clearout the other day a couple of 2 year old CDs totally didn't work because the sun had been on them pretty constantly. Had changed colour and everything. Refused to load up.

Found this when I just did a quick search : "Not long, according to Herr Kurt Gerecke, IBM expert on data storage. Mr Gerecke told the magazine PC World that two years is about the average life expectancy of a burned disc, and if you keep it in a dark, cool place it might last for five.". The page also says about certain brands being better. Such as the gold covered ones. Also about comercial DVDs lasting 100 years, but they are treated differently.

Cheers

A couple is 2. Should always be 2. But you were right anyway, CD-R lasts about 2 years according to a few on here.

i agreee witht he vink meister.

If we dont have those kinds of files now we sure will if those get produced.

It would be stupid of them to release something that wouldnt be outgrown shortly, they would lose money! And apparently thats all they care about.

Sounds like a great number, but what I'm worried about is read and write speed, and right now the CD Read and Write speeds suck.

not with Vista new file system. (It does have a new one right? Or is that to come in the next one?)

Holographic Storage such as HVD's will be around long before anything like this is.

And, given that it's holographic, the materials will last for a lot longer

More photons = better exposure
Lower write speed = more photons
I have many CD-Rs from 1998 that are just fine. Only a few ( < 5%) have gone bad.

I always write the disks at 1/4 rated speed (i.e. 48x speed discs @ 12x )

Most of my old discs were written at 2x.

I'd be surprised if a 56x disc written at max speed would hold all the bits for long.

I'm unique, just like everybody else.
