>Do they make hard disks that big? *:) The largest unit of data measurement I can find is a yottabyte. 1 yottabyte = 1024 zettabytes 1 zettabyte = 1024 exabytes 1 exabyte = 1024 petabytes 1 petabyte = 1024 terabytes 1 terabyte = 1024 gigabytes So, 1 yottabyte = 1125899906842624 megabytes. Enough to store 214,212,311 years of CD audio recording. Terabyte storage is becoming increasingly common (I'll have close to that at home by the end of the year), and petabyte is not unheard of. We're gonna need some new numbers soon. >P.S. Can I fast track a couple of complaints when you're up and running? Yeah, just remember that they cost twice as much before 9am. Seb.
