Currently, you can get a western digital WD1600AVJS from amazon for about 20 dollars. That is a 160GB drive. And the problem is not so much that you cannot buy smaller drives, but that they are not cheaper. Also, something like a seagate ST3000DM001 is currently something like $80-$90. That's a 3 TB drive. But if you have criteria which the smaller drives satisfy and the larger drives do not, you might get one of them anyways, even if they cost more? On the other hand an existing drive that you don't have to pay anything for is probably even cheaper (though when you start looking at how much it costs to power the thing, it's still not free, and at some point it might have been cheaper to replace it with something else. But getting long term power costs on a drive takes a bit of work, and it's often even more difficult to obtain those numbers for a drive you haven't bought yet. Thanks, -- Raul
