Where to start so many things are fixed with this Beta,  I use this primarly on my work laptop with a docking station, I keep a 1 gig USB drive in the dock and undock many times throughout the day.  The beta has fixed my issue where my video would not properly restore once redocked, and once I had undocked before it was no different than pulling the USB drive directly out instead of disabling it, now it disables automaticly “safely”.   The boot up time was tremendiously fixed, it was using a burst mode before manybe loading 20-30mg per burst of cache per second, takeing a good 10-15 seconds to burst fill the ram Cache, now its a steady stream of data flowing from the hard disk to the ram cache, about 1/2 the time of before directly limited by the speed of the harddrive now.    I had not used the Application Priority before, added my apps in there didn’t see the significance of that but will keep testing. 

Enhansment request:    If it could be implemented easily, I’d like to know on which USB controller a drive was mounted so that I didn’t have multiple drives on the same controller sharing the bandwidth, possibly a suggestion pop-up to alert me to plug seperate usb drives into seperate  controllers.
