Maybe I'm the odd one out but I don't see the perpetual need to have the enormous amount of space some folks around here strive for
500GB is way more than I'd ever need. Just as an example.
Then again, I don't store a lot of music/pictures. Mostly just application coding.
Yeah, actually, until I moved overseas and had to convert all my CD music to digital (FLAC files, which use a lot of space), I wouldn't have had such need for so much space.
Now, all my music is played into my stereo via my PC, so I'm glad I have plenty. Having said that, I would never need 16 TB. I have a 3 TB and a 1 TB drive, and a 85 GB SSD for my OS and apps. Even with a lot of video files and music, I've got tons of available space for growth.
