One of my colleagues was throwing out an old iomega 250 MB Zip drive yesterday which took me back to the days when storing digital data was expensive and often complicated. Until the mid-1990s there were few options beyond the 1.44MB floppy disc if you wanted to move data between non-networked computers. This wasn't normally a problem as we did not have digital images or video or MP3s to worry about. Loading software was another matter and often required the use of multiple floppies until writable CDs came along. My first laptop in 1997 had a 1GB hard drive which was more storage space than I thought I'd ever need. Happy days.
Anyway, I did a bit of digging around and found some historical data on the falling cost of computer storage and this table shows the dramatic reductions since 1980. (http://www.statisticbrain.com/average-cost-of-hard-drive-storage/)
The iomega Zip 250MB was launched in 2001 and approx. cost £150 (about £220 in today's money) with discs costing £10 (£15 today) each. You can buy a 32 GB USB 3.0 32GB today for around £12 which equates to about 10 pence per 250 MB and without having to pay £220 for the drive. Nothing we didn't already know but its sometimes worth thinking about how technology has changed in such a short time.
