The controller doesnt add that much cost, its the size of the memory in it to make that much space. This is why samsung started playing with tlc memory and it saves some money versus mlc. Tlc is slower, but also has less writes. Mine you, better controllers do cost some, but right now they know if the people complaining cant afford 120gb drives, their is no way they can afford 1600gb. The price is not even that outrageous knowing how many benefits ssd gives you over hd. Not worrying about hd randomly dieing is worth alot...let alone programs opening instantly and low boot times.
