That's right, but your drive is capable of FAST-40 and the controller is capable of FAST-20. They should negotiate a FAST-20 (40MB/s) transfer contract, but
because the drive is doing weird stuff, it keeps falling back ... until it
reaches async, which is just about the slowest contract defined.

the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince
himself that the war is just, and will thank God for the better sleep
he enjoys after this process of grotesque self-deception." -- Mark Twain
