[ExtremeTech] Harvard cracks DNA storage, crams 700 terabytes of data into a single gram - Page 5

post #41 of 101
I work with sequencing on a daily basis and currently the fastest ways of doing it require massive $800k machines (ABI 3730xl or 3500xl) which process up to 96 samples at once via Sanger Sequencing over the course of an hour. However this only applies to a sequence that is at most 600 base pairs long, not the massive 1 gram of DNA Harvard mentions (I usually quantify samples in the pico-gram/micro-liter range). Currently the average bit-rate would be about 1bit every 6 seconds with Sanger Sequencing (including machine warm-up time which is about 20 minutes in the 1 hour run). Other next generation sequencing techniques include Nano-pore and ion torrent which as mentioned have their issues reading sequences with many repeated base pairs (i.e. GTCAAAAAAGAAAAC where the G could blend with the A's).

While this may prove viable it will take quite a long time for machines capable of sequencing DNA at rates comparable to even CD's (1.2Mb/s). Don't even mention SSD's.

SSD's are powered by flash memory, keep that in mind. Do you mean a DNA/Flash Memory Hybrid Drive?

Wonder what the access time DNA memory could have.

I guess this could be the last step in digital computing/binary data before we move into quantum computing?

Who reads and writes 700TB aside from google maybe tongue.gif

What I find amazing is that a single strand of DNA has all the information your body needs to do build itself, and that's FAR less than a gram. Mother nature is insanely efficient in ways we can't even come close to, yet.

This. It simply amazes me.

That is probably what we would call cancer.

And also why not set each type to something. Eg. T = 11, G = 00, A = 10 and C = 01?

Isn't DNA not really living? It's more like mad cow disease. You can throw it into the sun, you can come back in 10,000 years, and if it's not 100% charred or rotten it's still the same as when it was produced/created/whatever?

But if they can stored 700TB in one DNA why come cant remember anniversary?

I found a video which helps to explains DNAs to me, but dont take my word for it!

Well, good luck getting as efficient as the universe, you'd have to somehow make the storage device a fractal. tongue.gif
