    They have 160 TB of disk and 24 trillion (6.67 bytes/password). They are getting closer to 3 bytes/password. Once you start going less than 3 bytes/password it gets kind of slow. They used to have 80 TB of disk and 7.8 trillion (10.26 bytes/password).

Honorable mentions:

If someone wants to give me a 4U server with 24, 4 TB hard drives in it (or around $6,800) I could totally be number one.
