1 TB has enough data for every man woman and child who ever lived to write a 1500 page book!
That's awesome and all ... but this isn't 1988, and we're not storing just text files any more. Nobody is writing 1500 page books to fill up their hard drives.
My iTunes folder is around 400GB, which includes my music and any digital copies of movies I've gotten. An HD version of a movie rings in around 5GB or so. I've still got dozens of DVDs I plan to rip so I have them on-line.
I just recently bought about 60 CDs which I need to rip, and the next BluRays I buy will include digital copies. So, realistically, I'll add another 100GB or so in the next few months.
I have about 100GB of photos, because I have owned digital cameras for the last decade.
I know people with children and HD video recorders who have massive amounts of pictures and videos. They blow through space like you wouldn't believe.
nd please do not give your niche use case in a reply
if you think my use case is niche, you're either clueless, or still only holding onto a bunch of text files.
My 2TB HD is about 50% free, and gets backed up to two separate 2TB HDs. I expect to be more like 40% free within six months.
But do I know a lot of fairly normal people without overly extreme data requirements who can blow past 1TB pretty fast.
So, I think your assertion nobody is using that much space is pretty much unfounded.
Seriously, look around you at what people are actually doing with computers. It might surprise you.
But, hey, like your namesake ... 640K ought to be enough for anybody, right?
