That's $1.60 per GB.
The raw cost of a single new disk does not apply, in any direct way, to expanding the storage capacity of a server. Say I have 6 36GB disks which cost me $100 apiece (USD600 / 216GB USD2.78 per gigabyte). Naturally, I put them in a RAID-5 array, for 180GB usable space. Now we're at $3.33/GB, not counting filesystem overhead. This is a realistic server configuration, not the pricewatch.com 180GB special for storing Vorbis streams at home. "Just drop in a cheap IDE disk" is not a realistic solution for this application. -- - mdz
