I moved into my first home in 1998.
I had a huge vinyl record collection which I had collected from 1976 onwards, consisting of approximately 15,000 units.
Unfortunately the room that held my vinyl records was inundated by flood water from Katrina in 2005. I was heartbroken (although I did get a huge tax write-off for uninsured losses). Also when I moved to my current home, I didn't have to move and store the roomful of vinyl (a huge heavy task)
Over the past year I have been ripping and downloading music files for my music server.
By my estimates, I now have 2-3 times as much music as I had in the roomful of vinyl on a single 2 terrabyte external USB drive.
Somehow in 1998, I never thought that the roomful of vinyl could be reduced to the size of a book. This makes backup possible and future loss much less likely. Also, moving this amount of music is effortless.
Technology is still surprising to me.
