Unicorn ACSI-USB adapter speed ?

[Petari]

There is ACSI-USB adapter Unicorn (AlanH) where can use some Pen drive as storage. But as I see, it can not autoboot with TOS because needs some initialization of USB port first. So, maybe is worth to add autoboot code for it in modded TOS . Maybe I will order one, but only if it has some good speed .
So, owners of it, please let us know what is transfer speed of Unicorn in hard disk mode .
May use this for measuring: http://atari.8bitchip.info/ahpt.html

I'm not home for the next two weeks, but will measure when I'm back home. I really like my Unicorns, but they're slow. HD-streaming demos don't work etc.
