The recent development of the 1TB hard drive reminded me of my first thoughts about the end of the hard drive expansion. Back when the 1 GB drives came out I calculated my total lifetime media need. It came out under 10TB and half of that was video:
1TB 200,000 books at 5MB/book (every book I’ll read or know about)
1TB 200,000 songs, 5MB/song (every song I’ll ever hear)
3TB 3000 movies, 1GB/movie (every movie I’ll watch or desire to watch)
1TB 300 TV show seasons, 3GB each (ditto)
1TB 500,000 photos, 2MB/photo (every photo I’ll take or see)
1TB 2000 hours home video, 500MB/hr (fun to shoot, but who will watch it?)
0.001 TB (every word I’ll write, email, publish)
0.1TB 1GB/year (saved email and internet cruft, LOL cats, etc.)
It sums up to 8TB/life. And indexes, you definitely need indexes, so say 1TB for indexes.
This will expand as high res video/photos phase in but even that won’t push this out much beyond 100TB.
300 TB would allow you to record your entire life in video for 16hr/day for 100 years at 500MB/hr (one camera angle). No compression for time spent watching your self-video is assumed. :)
