Some 100 times+ compression, very fast and also at very low power (because it was inside the brain), and lossless.
And not stated but because it was inside the brain, I assume possible memory usage also wasn’t that high etc. Sorry have no direct link to the specs.
The multi-electrode systems at the lab I worked in 2009 used a fiber connection to the host PC and generated terabytes of data, for just 128 or 92 electrodes (I forget) at not-all-that-many samples per second.
Sorry what is the point here? Or do you just want to share a cool story about data transfer? (I’m not trying to be snarky, I feel like im missing something here).
Just an example of the data involved in a brain-computer interface.
