Wow - big enough to hold a whopping 10 BluRay discs!
Sarcasm aside, that points at the issue: no matter how much storage you throw on a machine, it's still not enough to hold your whole digital life without selection, pruning, and maintenance. Far easier (maybe cheaper) to give $50/year to someone to give you all but unlimited storage, rather than having to upgrade to the next bigger drive each year and fiddle with moving everything around (I'm trying to shuffle 5 drives onto 1 new 1TB pocket drive; hassle!).
250Gb is plenty for my purposes.
I have no desire to trust Google with my data. I know they do not respect anyones privacy. I’ve also tried their online apps. Feature rich they are not. They also fail in the dependability department.
