500TB of data can be stored on a CD-sized glass disc using 5D storage technology

At a writing speed of 230KB per second, that's 96 years to fill up the drive

 

That basically kills it. Even regular HDs do 150-200 mb/sec, so not sure how useful this tech is.

 

I remember reading about this technology on Ars some time ago. The big advantage to this technology, and the material it's written on, is that it lasts an extremely long time with data integrity not being compromised. So for the likes of the film industry that spends time and money copying movies on to other media, as they degrade over time (even film reels are stored in salt mines), this is great archiving technology.

 

It did not kill anything. He pulled 230 KB/s out of his ass

 

No he didnt pull it out of his ass, I googled it and found reference to it here. Whether its accurate or not, I dont know.

Also states this?

typo? or is it 230KB/s written in parallel many times to speed it up?

rough maths 60 days for 500TB is about 96 ish MB/s speed

 

This obviously is still a study and needs further development.
I'd welcome it very much to store data reliably to keep stored safe.
I doesn't even need it to have 500TB density, 10TB sized CDs are plenty enough so people can afford it.

 

It's a cool idea and if it can be easily distributed, it would be a great solution for long-term archiving. No need to try to make it sound fancier than it really is by needlessly shoving the word "nano" everywhere...

 

I'm really excited by this development. Feel like investing in this one tbh.

 

All my porn on one disk...Cool.

 

that's a slow ass transfer rate

 

I haven't read so much impenetrable tech gobbledygook in one story for a long while - reads like a script for some Marvel Universe movie

 

This has to be the most over the head stuff I have ever read.
The techno jargon is over 9000.

 

No typo it seems, just some good weed on the research campus.

"The researchers used their new method to write 5 gigabytes of text data onto a silica glass disc about the size of a conventional compact disc with nearly 100% readout accuracy. Each voxel contained four bits of information, and every two voxels corresponded to a text character. With the writing density available from the method, the disc would be able to hold 500 terabytes of data. With upgrades to the system that allow parallel writing, the researchers say it should be feasible to write this amount of data in about 60 days."

So with potential and currently non existent upgrades of parallel writing at 230 KB/s they estimate it should be doable in 60 days. For it to be feasible in 60 days there has to be 428 instances of parallel writing to a single disc at 230 KB/s. How do they intend to do 428 parallel writings to that small of a disc i got no clue, presumably the device that does that needs to have 428 writing heads?! Weird.

 

The astronomical burn times and purchase price!

 

It's like the typical 428 head DVD burner we all have on our old computers. And if it's a 20x 428-head burner, that would reduce it to a mere 3 days!

 

5D is so old, 6D rules.

 

It certainly sounds like the drive would cost a million bucks if it requires 428 writing heads, as the article didn't make it sound too simple even with a single writing head.

 

You guys are thinking too conventional. If human ingenuity has taught me anything it is that we, with time, will figure it out.
