3gb/sec read and write speed, about $4,700 for 15tb for these datacenter class hardware. So in about 3 or 4 years this will be less than a $1000, probably getting smaller, closer to a consumer product. There's an old sf book about recording your whole life, we aren't quite there. At say 15 meg per sec (from a random site about 1080 dashcam video [1]), 86400 secs * 15 meg / 1024 / 1024 = 1.24 tb per day. Assume another 50% improvement by h265 and you still have about 600 gig a day per lifetime recording.

Life-recording video is much more compressible than Dashcam.

No reason to record oneself sleeping, in the bathroom, or reading a book 99% of the time. Slap some ai or sound/vibration/motion/location logic into the camera and I'll bet there's maybe 8-12 hours a day on average remotely worth recording. Assuming: 78.5yr lifespan 3200mbps/400MBPS@60fps 4k video (Sony fsm72) for 8 hrs of video a day yields: 5.50128 petabytes over 78.5yrs. Or 687.66 8TB drives. At $155/drive that's $106,587.3, or 1,357.8/yr at today's prices. Assuming a 1.666r% price decrease per year, the final years drives will cost approximately $41.8. Taking your 1.24tb as terabits, div 3 and applying the same pattern as above I get 1480.379166TB, 185.05 drives, rounded up, for a cost of 28,830 in today's dollars. Hope my maths right..

You're confusing megabits with megabytes. The correct number for your example is 162 GB per day. For reference, a 4K Blu-ray runs about 100 Mbit/s, and requires 1.08 TB for 24 hours of content. (395 TB for a year.) Netflix streams 1080p content at around 6 Mbit/s, and requires 64 GB for 24 hours of content. (24 TB for a year.) Note that both of those examples are 24 or 30 fps. If you turn off the camera when you sleep, multiply by 2/3. If you use hard drives and don't mind 6Mbit/s encoding, it's pretty cheap. Hard drives currently cost about $20/TB, so a year of 24/7 video would be about $500. Multiply by two for redundancy, and you get $1000. If you cut video of yourself sleeping and you massively compress "boring" sections of your life, then it seems plausible one could do it for $200 per year (or less, depending how boring your life is, or how much you care about preserving minutiae :-) ).
