The read/write speeds are not great. We're talking about bytes per second. Then again, this is more of a "proof of concept" than anything else. If this ever got to see the day of light within commercial products, we would be talking about some other, much more sophisticated system for reading and writing than is available today. Still, it's pretty cool that the core of the idea actually works with satisfying results from a storing data point of view. Now, we need to see some hardcore RAIDing going on here.
What I always wonder about when I see stories like this are the details of the implementation: What is the throughput on write and read, what is the failure rate on writes and reads, how large and efficient is the system around the storage device...
The last is particularly is relevant to max's comparison: A hard drive is a complete write/store/read system, but the DNA strand is only the storage. A fairer comparison would be the weight of the magnetic material on the platter surface (the substrate is just a carrier, in the way the agar slate or whatnot is only the carrier of that DNA strand), and I'm guessing we're actually already storing 4TB on less than a gram of media -- but that media is almost valueless and incredibly difficult to use without a properly rigid substrate, motorized access system, servo-driven read/write, relevant electronics and secure housing.
