== Summary ==
[[Personal Computer]] [[hard disk]] capacity (in [[Gigabytes]]) over time. Data culled from [--www.littletechshoppe.com/ns1625/winchest.html]. 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 [[User_Talk:Dantheox|talk page]].
