You have a laptop encoded with RC4 ( who in the world uses a stream cypher

You'd use it for hard disk encryption, by re-keying it for each
cluster of 8 kbytes or whatever. I've seriously considered this
method since it should be much faster than AES.
And as soon as you rekey, the bias is no longer there. You HAVE to encrypt
the whole of the 160 GB with a single key to take advantage of the biases
as far as I understand the attack.
By the way, how in the world do you keep track of 10,000,000 keys?
Key + IV, with the IV being based on which 8kb block you are working on?
