| 3 | Hard drives used to have capacity measured in MegaByte~s -- these days it's in GigaByte~s (but also see the MebiByte and GibiByte pages). | ||

| 5 | A typical cheap [IDE] hard disk drive these days might cost around NZ$120 for 40-80 GigaByte~s of data (about $1/Gb for larger drives). [SCSI] drives are typically slightly more expensive. | ||

| 15 | AristotlePagaltzis | 9 | To appreciate how far storage technology has come, look at the size of [a 4 megabyte disk platter | http://www.wlug.org.nz/archive/images/platter-lowres.jpg?] used at StanfordUniversity in the 1960s; there a $1 note in the lower-right corner to give you an idea of the platter's size. The black mark around it is from a disk head crash (!!). |
