I dug around a bit and found a research paper[0] about TerraServer. It's got all sorts of neat details not in this link.
TerraServer hardware configuration parameters:
Max hits per day 40 million/day
Max SQL queries per day 37 million/day
Max image downloads / day 35 million/day
Bandwidth to Internet 200 Mbps = 2 Terabytes/day
Concurrent web connections = 6,000 connections
Web front ends: Six 4-way 200 Mhz Compaq Proliant 5500, .5GB ram
Database back-end 1 8-way 440Mhz Compaq AlphaServer 8400 10GB ram, 3.2 TB raid5
324 9GB Ultra SCSI disks
324 x 9GB disks for 2.9TB? You could store 1.2PB with the same number of 4TB disks. Doesn't seem like Moore's Law is holding up for storage, nor for internet speeds.
