Back in the day I used to spec disk storage (e.g. EMC Symmetrix) at around $1000/GB. Then I spent about 2 years away from the system sizing game. When I got back into the flow in Feb 2002 I looked around to figure out new rules of thumb for storage costs. On a continuum from cheap to pricey:

"Back in the day" I used to spec disk storage (e.g. EMC Symmetrix) for customers who paid around $1000/GB. Then I spent about 2 years away from the system sizing game.

Raw IDE disk (Maxtor) 120GB $120 1 Compusa

mid-range RAID (Sun T3) 1321GB $98k 74 Sun Store
high-end RAID (Sun 9970) 9TB $677k 73.5 Sun Store

Now high-end RAID is about 75 times more expensive than consumer-grade IDE (the difference used to be 25x). It's getting harder and harder to justify going with the big stuff, unless you really really need it.
