Holographic Storage Crams in 0.5TB Per Square Inch
An anonymous reader writes "VNUNet is reporting that a company called InPhase Technologies claims they have successfully recorded 515GB of data per square inch to capture the record for highest data density. From the article: 'InPhase promised to begin shipping the first holographic drive and media later this year. The first generation drive has a capacity of 300GB on a single disk with a 20Mbps transfer rate. The first product will be followed by a family ranging from 800GB to 1.6TB capacity.'"
I suggest you read Slashdot
300GB capacity at 20Mbps... Can someone check the math on that? I'm thinking overnight backups aren't even going to be possible.
Well, it really doesn't. The only people who NEED terabytes or more can already afford that much in hard drives. But that's mostly what the summary mentions. That and data density by physical size... which isn't really that important.
...and so on. Those areas are where advances could REALLY make a difference.
What I want to know is, how does this technology stack up against hard drives or other existing technologies on issues like
- Data read speed
- Data write speed
- Power consumption
- Heat and/or noise
- Size and complexity of read/write mechanism
- Resistance to physical damage
- Rate of data decay
Sounds slow:
...hopefully writes arent slower
> 20Mbps transfer rate
which equals about 2.5 MBps (megabytes per second). It would take about 8 days to read a whole 1.6 GB disk
And the density sounds like half a terabit, not terabyte:

> In April 2005 we demonstrated 200 Gb/in data density

Not really. BluRay and HD-DVD discs can be mass produced in R/O form. This won't be a replacement for either of those technologies unless it's possible to create multi-million impression runs on an assembly line -- which it currently isn't.
Dear InPhase, please STFU and ship this shit already. This is the 1000th pointless article I've seen about this on the last two (is it three now?) years and I'm getting tired of hearing about it. I've got data that needs backing up, and whoever comes out with a 50+GB/item WORM non-tape media first is going to get my cash. At this point I use hard drives to back up instead of tapes because they cost far less per GB than the damn tapes do.
Hell is being intelligent in a world full of idiots.

There's a lot of talk about how slow it is, how it doesn't contain that much data especially compared with one of those 500 gigabyte hard drives... etc etc etc
First, this is one "plate" compared with 5 plates of the 500 gig hard drives.
Second, this is a first generation product. The first CD-Rom was incredibly slow. The first DVD-Rom was incredibly slow. The first 3.5" hard drive was incredibly slow. See a pattern? This is probably going to be marketed toward those industries that use DAT tapes. As they incur most of the initial costs, the technology will improve, densities will increase and costs will fall. Is there anyone paying 400$ for a 2X CD-recorder nowadays?
Plus, these aren't being sold to consumers until 2008 which is a good decision because it allows the technology to mature.
Will these replace hard drives? In my opinion, not until 2011, sometime around there. That's when perpendicular hard drives (+ onboard flash) will reach maximum density compared with cost and holographic drives will dip under the HD price point. Considering that the industry is moving toward 2.5" HD drives as a replacement for 3.5" HD drives, holographic storage (let's start a new acronym: HS) will offer even more storage on a technology that should be hitting full stride at that point.
But this depends on HS random access times and how the research is heading toward flash memory. Flash Storage might be a competitor to HS around then.

No. Moving. Parts.
The comment... not funny.
The +1 interesting mod... funny.
The funny thing is, it's the porn industry that is the first to ship things in new formats. While *I* wouldn't mod the above comment as interesting, it stands to reason that good quality porn was the reason many bought into 16mm, super8, beta/vhs, and DVD.
So yes, a mod likely has a porn collection that spans so many DVDs they would very much enjoy a new space saving format that is equal or better in quality... for their HDTV cum shots, and 60 inch projection vaginas.
I better go AC.
Keep in mind that the summar is completely wrong. By a factor of 8. The drive is not half a terabyte, it's half a terabit. There's a difference. Same thing with the transfer speeds. It's no wonder that the general population is confused about storage space when a slashdot article gets it flat out wrong.
