Universities in Germany put 500GB in one DVD, claim 1TB is possible

are all you guys obsessed with porn? you guys have no lives.











and neither do I

Freakin' sick!

Nah I just like to make porn jokes..

 

[russianboy]

I can store hours of my newest favorite song!


you spin me right round right round like a record baby right round
you spin me right round right round like a record baby right round


no more of having to go to meatspin to get my fill!

No we just all like pr0n

I actually remember reading about this about 2 years ago when they first attempted it. from memory it had something to do with them making small (friggin tiny) pyramids on the discs surface and recording on all four sides or something like that... pretty amazing.

Imagine if the receptionist lost 500gb of company data on the way to work!!!!! that is a lot of info for someone to get their hands on.....

It would suck waiting 4 hours for the thing to burn too...... HAahaaa

 

[TXcharger]

4 hours? is worth it for 500 hours of porn haha jk

If they can jam more data into less space, they wont need to spin real fast will they

Yes, they would. It would take a year to get to some of that data if the read-speed didn't increase.

You guys are silly.



Aerial density means that the drive can spin SLOWER to achieve the same performance. Anyone heard of perpendicular recording drives? Same RPM but much faster reads and writes. Same reason when the craptors came out a set of them in RAID was then and still is slower at sequential reads and writes than two higher capacity drives.


RPM is only good for access time, IE a few MS of seek time, aerial density is good for more data transfer per second. Yes data transfer does go up with speed, but not as much as it does for higher density drives.


Go look at our HD tach benchmark thread.


Or compare.



Writing speeds for DVD were 1x, that is 1350 KB/sec


Note that for CD drives, 1x means 150 KB/sec, 9 times slower.

two words = enterprise backups

I was thinking that, right now our NAS is only running 500gb, LoL.

Oh, hd dvd. I was gonna say, it would be even more remarkable to have 500gb on a DVD (change thread title?).

Second that!

I'm glad I'm not the only one that has read about major data increases on HD DVD format.

Thank you, someone needed to clear that up for people!


Blu-Gay . . . what was that?? 8-Track?? (sorry I had to, its Sony
