The flip side

Renugopalakrishnan says making large amounts of information so portable on high-capacity removable storage devices will make it easier for information to fall into the wrong hands.

"Unfortunately science can be used and abused. Information can be stolen very quickly," he says. "One has to have some safeguards there."

In conjunction with NEC in Japan, Renugopalakrishnan's team has produced a prototype device and estimate a USB disk will be commercialised in 12 months and a DVD in 18 to 24 months.

The work has been funded by a range of US military, government, academic institutions and commercial companies, as well as the European Union.

It's too early in the morning but I will try...

1. I wasn't saying that I can prove that a CD/DVD will last 100 years. If you read my post, I pointing out that with "accelerated aging techniques" one could ESTIMATE the longevity of a CD/DVD. I provided a link where you could read more about it.

Here it is again:

"...If you read the article they said the bacteria was already modified to last in it's intermediate state "more than a few years". I don't know if you read that far before posting..if not you might want to go back and check it out. Which brings me back to the original point I made after you complained about it losing it's intermediate state."

Yes I did read the article. How long is, "a few years?" That's problem number one. Problem number two is the heat. They did not mention the temperature at which the bacteria would start to die. Which means this is not good for long term storage.


"If it can stay in that state for many years it's life is no different than that of a regular hard drive. They just die in different ways. For a bacteria it begins to return to it's ground state..for a hard drive it eventually fails because of bad sectors..mechanical failure..etc. You continued to complain that it doesn't last forever...ie.making the same argument as before which i again addressed."


1. How quickly does a HD begin to die? Are you telling me a HD will die in a few years? If you HD is dead in a few years then you have a defective HD. HD's are coming with 5 year warranties. Thus they should last at least 5 years.

2. I said nothing of the bacteria storage lasting forever. In fact we have no idea how long it will last. My criticism is will it last as long as a DVD. We can ascertain how long a DVD will last but we cannot determine how long one of these bacteria storage systems would last. The researcher was pointing out using this new system as a replacement for DVDS. Unless the new system can last as long as a DVD, then they will not replace DVDs for storage.

It is presumptious of the researcher to say this is meeting the need of storage. Quote:

"You have a compelling need that is not going to be met with the existing magnetic storage technology," he added.

There are significant hurdles to over-come. This new system is hardly a replacement anytime soon, if ever. There are already new technologies coming out that will increase the storage capacities into the Terabyte range. Until we have more information and a working product, this is vaporware.

Very few technological inventions are home runs. Rather, the information learned is combined with other information which leads to more invention and eventaully everything comes together to form a commercially successful product. Keeping with the baseball analogy, this technology will likely be like a bunt, or a sacrafice fly used to move a runner, but not to score a run. Getting into arguements over this proposed product is a bit premature, I think.

The fact that they can even get this to work is pretty darned cool. There has been talk about "biological" computers for some time know, so its interesting to see some of the progress made.

If something like this ever did go to market I bet PETA would protest

Gee, I wonder if cleaning your disks with alcohol will kill them?


OK, I'll go to my room now

they need to apply this technology to current dvd's so my rentals will deteriorate rather than me having to bring them back!..
