One Trillion Bytes What gets smaller as it gets bigger? Hard drives, of course. Maxtor just released the 1TB OneTouch III Turbo (that's not a misprint: 1 terabyte = One trillion bytes, one million megabytes, or one thousand gigabytes -- more or less). The external device is really two 500GB drives which can be configured as a RAID 0 or RAID 1 mirror. As its name implies, it also comes with its popular OneTouch backup button.
