- Actually, this isn't quite true. If one considers the lifetime of a disk
- drive and the lifetime of an article, you get
-
- the drive: 4 years [*] = 52 * 4 weeks = 208 weeks of life
- the article: 2 weeks [*]
-
- i.e. that 100MB you're using up is 1/104th of the total usefulness of
- the uber-drive's lifetime; assuming that you use up 100MB of a uber-drive,
- and assuming that the uber-drive was bought retail at today's prices as
- an aggregate of 2.1 gig scsi shoeboxes from the Computer Shopper [*],
- your article would cost $1.50 a megabyte to store, you'd be storing
- it for 1/104th the lifetime of the device, and the quantity of your
- megabytage would be 100.
-
- 100 * 1/104 * 1.50 = 1.442307693 (approx)
-
- so, assuming that my figures are close to correct, your posting a 1k article
- would cost the net approximately eight packets of Top Ramen (6/$1.00) plus
- enough change for some cheap gum.
-
- [*] indicates a place where the data is not guaranteed to be valid by any
- governing authority. In particular, I went low on the drive life estimate
- and assumed two-week expires on average for the average usenet group; this
- is what I did when I adminned news, your experience may differ. Also,
- disk systems range in expense; I imagine that one might have to pay as
- much as $3 a meg for certain drives, in which case the cost-per-article
- is up to nearly $3.
-
- If someone finds ridiculously stupid errors in my article, feel free to
- point them out gently on the net and flame me in e-mail. :)
