View Full Version : 25TB titanium oxide 'super discs' in the works?
Japanese researchers have discovered a material that could be used to make low-cost discs with a storage capacity that puts existing storage media to shame. Described as a new crystal form of titanium oxide, the material switches from a black-color metal state that conducts electricity to a brown semiconductor when exposed to light, according to Shin-ichi Ohkoshi of the University of Tokyo. That transformation occurs at room temperature and provides an on-off function for data storage.

i am not expecting one of these in the next 8 years.
I dont even know what to do with uneraseable disk with 25TBs.
imho a 25TB-HDD would be good, maybe for 100 $ each.

Thats 5844 DVD5s, thats a whole lota space. Maybe 10 years time? by that time holodisc will be competing with it
whatever it may be, hopefully we can get a higher level of data availability/readability/durability without having to worry about TB's of lost data due to some unexpected external factor or internal malfunction :rolleyes:
That's actually enough to include all of anon's porn.This way he won't buy DVDs anymore
I have a "phobia" from storing on disks (although the hard drive is a disk as well :tongue:) but I mean portable disk because the chances of them getting corrupted or lost are high even if you look after them. However, I could do with a 25TB hard drive

Suicidal :biggrin:, what will happen if the disk brakes, 3 years of "torrenting"
Anon always makes backups don't worry:biggrin:

Are you sure ?
Why don't you ask him?:unsure:

If the disc brakes he I will just pick it up.
Now, if it breaks... that's something different. :lol:

Would you rather carry a 25TB DVD size dics or a micro sd 250GB?

Do you know hard is it to lose a 250gb MicroSD-Card,
it is that big as your finger-nail of your little finger. :smile:

yeah but u could put it in ur wallet or something. eventually they will and it would so great to have
Would you rather carry a 25TB DVD size dics or a micro sd 250GB?
The DVDs, because of the higher storage space. MicroSD cards could be easily lost like tokiodrift1, but I wouldn't be carrying them everywhere... so more space = win-win.
Anyone know what the costs of these discs be? I hope they have rewrittable discs so i can use them as a hard drive.
"A lot" is probably the correct answer :P Even dvd-r's are still insanely pricey compared to getting a new hard drive
Damn, well either way, wait a year after its release and it should be considered as dirt cheap. Thats how all computer equipment works.
Yes and no, as I tried pointing out, stuff like dvd-r's, br-r etc are all insanely expensive. And dvd's are super old by now.
Probably because there isn't as many innovative thinking going on in that area as for instance, hard drives, that regularly get updated to bigger versions. I guess this disc will come out pricey and stay that way for a long time as I don't see any new updates coming there soon.
It's always been cheaper to buy a standard hard drive for a given quota than buy dvds or blue ray discs. I'm guessing this will be no different. Rewritable discs have always been even worse, for that matter.
The main reason that everything else in the computer world gets to be dirt cheap after a year is that it takes like 6 months ( ? ) to bring out a new and better version

BDs are stupidly expensive for archival purposes many more DVDs are sold more than BDs
yay, i'd be able to have a collection of movies in loseless video :D

For archival purposes, just buy a 2TB HDD. They're cheap enough as is :P
Anyway, so are DVD's though, just do the math! You would need 455ish dvds to burn all the data on a 2TB HDD. This is a generous calculation, having your files meet PERFECT conditions. This means that the dvds will be completely full. I think we all know that is impossible and you'll always have some spare room on the disk with nothing that fits.
Over here, one blank DVD-R roughly still costs 1euro. This would result in 455 euro in a perfect world. Maybe 500 in a more realistic world. A 2TB HDD costs like 110 euro here, meaning you could archive 10TB of data using HDDs for the same price as 2TB of dvds.

seems your calculation is off roughly by a factor of 5 :eek::
dvds:
$20~(100*4)GB (*5)
$100~2TB
hd:
$120~2TB

Well, that's because yours are somehow a 5th of the cost of mine. (factor 5, anyone?) Over here, you buy 25 dvd-r's for 25 euro. So my calculations are quite correct, sir :P You must not have read my first sentence. I admit that I accidentally used 4.5 instead of 4.7 for a dvd, but your argument is completely based on dvds being cheaper where you live, rather than me having faulthy calculations. :P
Also, seeing as they're hardly different in your case, I would gladly give 20 dollars more if it meant I didn't have to write 100 f*cking dvds, which would easily take a week of manual labour.
As a side note, in my case I'm paying 0.05 euro / GB in case I buy a HDD and 0.21 euro / GB in case I buy dvds.
In your case, that's 0.05 dollars / GB for a HDD and a shocking 0.04 dollars for dvds.
All in all, in your case you can just chose, in my case I'm obliged to go for the HDD
Well, that's because yours are somehow a 5th of the cost of mine.
doesn't that seem very strange/unusual to you?
when comparing these two examples, the hd prices are roughly the same (as expected) yet the dvd prices are more than 5 times higher for your example, seems you either have wrong info on the prices or the customers are being ripped-off by that shop owner(s), care to show some proof of pricing (the shop surely has web pages, right?)
furthermore, i'd say your example is more likely an exception which makes it unsuitable for overall comparison between (averaged) hd & dvd cost per GB
Lol really? You want me to prove that stuff costs that much here? Why would I even care about lying about it?
Okay here we go: Apparently they're even more expensive than I noted in my previous post. (http://tones.be/shop_product.php?idx=108850)

Yah. It does seem strange/unusual. But I've come to realize a long time ago that prices differ greatly depending on where you live. If I go to a neighbouring country, say germany, I would be able to get electronics, for instance in case of germany, a lot cheaper if I had the will to drive an hour or two there and again coming back.
As a matter of fact, you're only paying 92ish euro for that hard drive if you convert it while I pay 110.
This is life, get used to it :P

Still, even if it costs more or less the same, as it does in your case, writing dvds is a pain in the ass compared to ctrl-c'ing everything and ctrl+v'ing it again and just letting it do it's thing. Not to mention trying to find a certain dvd in a stack of 100 dvd's.
well, clearly a rip-off
the german prices (considering dvd media in the example) are roughly two times the usa ones and the belgian are roughly two times the german ones and it can rise even higher depending on the shop greed for profit (or lack of good connections to importers)
Still, even if it costs more or less the same, as it does in your case, writing dvds is a pain in the ass
agreed

And its no Problem to Order DVDs from Germany to Belgium... And you can get them even cheaper than in the US if you order larger quantities...
I rather not have stacks of dvds or cases lying around here. Trying to keep it clean here lol. Also, transport is often a bitch
Wow, this is really interesting to hear. I was thinking about making the shift to Blu-Ray soon, but seeing how BD-R's are still somewhat expensive. I no longer burn my media to discs, instead I keep them on my hard drives. I bought two more 2TB hard drives, and at the moment have 8TBs of space. Man, I remember download 2GB was a whole lot, now I tend to download HD movies, so it really requires me to pump up that extra space.

Those disks are a long way off from making their way to your home...
But the progress that have been made this year are tremendous...
I'm sure you know of transition of technology that has been going on and the sea change that will occur from the 1st trimester of next year...
FYI - 2011 will see biggest hard drive change in decades! | Geek with Laptop (http://www.geekwithlaptop.com/2011-will-see-biggest-hard-drive-change-in-decades)
There hasn’t been a great deal of news about it so far but soon our hard drives will never be the same again.
At the moment, our hard disc drives are formatted into 512 byte size blocks and have been that way for years but as from the first quarter of next year hard drive suppliers will start shipping hard drives with 4 K disc sizes.
All hard drive suppliers have agreed to adopt the 4 K size by the end of January next year through the International Disk Drive Equipment and Materials Association (IDEMA).
The biggest hard drives that are available for pc use I believe are
Seagate Breaks Capacity Ceiling With World’s First 3 Terabyte External Desktop Drive – Media Center (http://media.seagate.com/2010/06/seagatetechnology/seagate-breaks-capacity-ceiling-with-worlds-first-3-terabyte-external-desktop-drive/)
SCOTTS VALLEY, Calif. – June 29, 2010 – Putting more terabytes in the hands of consumers worldwide, Seagate (NASDAQ: STX), the leader in hard drives and storage solutions, today announced the world’s first 3 Terabyte (TB) external desktop drive. Available immediately, the 3TB FreeAgent® GoFlex™ Desk external hard drive helps to meet the explosive worldwide demand for digital content storage in both the home and the office. With 3TB of capacity people can store up to 120 HD movies, 1,500 video games, thousands of photos or countless hours of digital music.
Samsung's faster EcoGreen F4EG hard drive does 2TB for less -- Engadget (http://www.engadget.com/2010/08/03/samsungs-faster-ecogreen-f4eg-hard-drive-does-2tb-for-less/)
Samsung latest 3.5-inch EcoGreen desktop hard disk does with three platters what its F3EG did with four: obtain a 2TB capacity.
Obviously then Hitachi has to have a say in it
4TB hard drive: Hitachi preps for launch | KitGuru (http://www.kitguru.net/components/hard-drives/faith/4tb-hard-drive-hitachi-preps-for-launch/)
We’ve all got our ‘I remember when they launched the X capacity drive’ stories. Some memories begin with the 5MB Winchesters, while others didn’t start noticing that size does matter until Hitachi and Seagate went neck and neck over the line to launch the 1TB drive in May 2007.
Hitachi is now readying plans to unveil the 4TB Mars drive before the year is out.
One terabyte is good for me as long i dont make movie or music collections. I download stuff, watch it, cheat on it for a while, then delete and get something new. If you make a collection of something, you should probably deal with bigger capacity, 25TB would be freaking awesome :D . Also if you are doing some stuff with video or audio like rendering, editing etc., it's great. 1TB is enough for everyday use in my opinion.
I can fill my 1TB pretty quickly with Bluray HD movies, dont know how would it be with 25x bigger HDD :D
And that material should be cheap so probably a lot of computer users might get this kind on HDD's in the future.
