You could fill up your 1Tb hard disk with <1 second worth of of movie. ðŸ™‚
Of course in practice, your computer couldn't actually save the data to disk at that rate. I wonder how they manage to move the data from the camera to storage.

How many pixels/frame? Full colour or B/W only? Is that known?

Edit: pixel resolution = (450 × 450) Not even VGA resolution.

That's still 200,000 bytes needing to be moved off the camera every 4.4 trillionths of a second.
Assuming American trillions that's a data rate of 50,000,000 GB/s. ( 50 Petabytes per second).
I don't think any data-bus or storage system can handle that.
Even if you include compression on-chip, I don't think its feasible.

According to Wikipedia:
AT&T transfers about 30 petabytes of data through its networks each day.

Supercomputers: In January 2012, Cray began construction of the Blue Waters Supercomputer, which will have a capacity of 500 petabytes making it the largest storage array ever if realized.

Was that 500 Pb in ram or hard drive/ssd? That is a LOT of memory in any case!

My guess is that camera feeds a bunch of drives or ram in parallel, don't see how they could do it serially.

I think the solution is that it only takes a short burst of 6 pictures at a time.

Was that in the article? 6 frames?

which has pictures showing 6 frames.

If I understand it correctly, a sequence of pulses in different wavelengths is fired at the target. The result is then separated out based on wavelength to create the images.
