The Caboteria / Tech Web / DiskStorageCost (revision 1)
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:

type amount cost $/GB source
Raw IDE disk (WD) 20GB $100 $5 Staples
SCSI "shoebox" (Sun Multipack) 218GB $5650 $26 Sun Store
low-end RAID (compaq 4100) 432GB $15k $36 Compaq website
mid-range RAID (Sun T3) 655GB $84k $128 Sun Store
high-end RAID (Sun 9960) 5800GB $730k $125 Sun Store
