I wonder ... how many terabytes would it take to store just the 24/7/365 video of a 90 year lifetime?
What's a DVD and how does it work?
MPEG2, a format commonly used for playing video via computer, compresses one minute of visual data into about 30 MB. So a two-minute video requires 60 MB, and a two-hour movie requires 3,600 MB. Compare that to the maximum storage space of a CD which is about 640 MB.
Do the math at that rate.
3600MB x 12 (for a day) = 43200
43200 x 365 (for a year) = 15.7 mil
15.7 mil x 90 (years) = 1.4 trillion MB?
Check my math.
