With BIOS A05 07/26/2012, it takes 15.2 secs to get the password screen of the encrypted USB drive.
With BIOS A09 02/01/2013, it takes 2.3 secs to get the password screen of the encrypted USB drive.
That is a significant improvement.
Note that repeat attempts on A05 do not take 15.2 secs, more like 2.3 secs.
I leave to you the decision as to whether that is fast enough.
