36 GB drives should be more cost effective since you have to buy half the number to shelves to accomplish a data requirement...
Assuming I'm figuring this properly- you'd have to buy 8 shelves of 18 GB drives to accomplish 1 TB of data. Alternatively you'd only have to buy 4 shelves of 36 GB disks to accomplish the same 1 TB. In the end, the offset is much cheaper to go with the latter. Of course this assumes a rather large data requirement, this may not be true with say a quarter TB or less.
One caveat to keep in ming when buying 36 BG disks however, if you plan to create more than one volume on the filer. Smaller disk sizes will be more flexible since the minimum volume size is 2 disks you may have better luck with the 18's if you're planning for smaller volumes.
