I wonder how much storage space an hour of uncompressed, high-definition holographic video would take up...
Do we have that yet?
I'm not sure about holographic, but if memory serves me, 1080p at 60fps, 10 bits per channel, 4:4:4 encoded, uncompressed would run you about 1.5 terabytes per hour. But I hope you have the 444 MB/sec sustained throughput on your hard drive to be able to read or write it without getting jerky or dropping frames, respectively.
