The factual accuracy of this diagram or the file name is disputed.
Reason: 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)
