[edit] Legacy file information
Here is a copy of metadata about this image that got difficult to find after subsequent re-format from PNG to to SVG and then move to Commons. As of 2011, info can still be found at en:File talk:Hard drive capacity over time.png and en:File:Hard drive capacity over time.png. The gnuplot script needs some tweaking to produce SVG.

The factual accuracy of this diagram is disputed
The dispute is about: WARNING: This graph is highly misleading since it is based upon advertised retail products and at least in the 1980s misses the higher capacity drives which generally were not offered at retail. For example, the highest capacity disk drive listed and plotted for 1981 is 26MB while the actual highest capacity HDD then offered was the IBM 3380 at 2,520 MB per disk drive (2 HDAs per disk drive box). By the late 90s high performance drives were readily available at retail. Tom94022 (talk) 06:10, 25 March 2009 (UTC)

"Personal Computer hard disk drive capacity (in gigabytes) over time. Data culled from [1]. This is very much a first cut -- an improved image with more data extending further back in time would be much better than this. The spreadsheet I used is available; leave me a message on my talk page."
