They are talking about density (how much data can you put in a square inch) not full capacity of disk. For example: we here have 47Gb Seagate Elite Hard Drives... the only problem is that they are 5'1/4, double height. We also have 36Gb IBM Ultrastar 36XP 3'1/2, 2/3 height. The elite has ten disks while IBM only five. The diference in years betwen tecnologies is 3.
