I got that
I would imagine a 1TB disk or HD would be less reliable than a 200GB one...
Why?
I still don't see the reason why we need 1000GB CD's.
Well, I've got a 320 GB hard drive and a 160 GB one. That's roughly half a terabyte. I only need to double my storage and I will have a terabyte of storage. To back it all up onto one disk would be so handy. Add a few dozen HD movies and stuff, I'll start needing a second disk!
Storage always expands to more than people think they will ever need. Always. It has been that way since the 1960s.
