ESXI 4.1 very slow to boot with USB thumb drive

Hello Experts,
I tried to move ESXI 4.1 from the datastore my server VM is on to a USB flash drive. I plugged a new 2GB drive into an open port on the back of the host (IBM X3650) and proceeded to instal ESXI 4.1 on it. I noticed that it installed very slow and then booted very slow (only about 1/8 the speed of booting ESXI from a hard drive. I know that the throughput to a thumb drive is going to be much slower, but might this slow operation of ESXI when on the thumb drive cause some issues with the server?

On the BIOS settings check the USB speed settling and Legacy device setting.
USB port in Full-Speed mode supports just 12 MBPs ,where as in Hi-speed mode supports 420 MBps.

Thanks Guys,
I thought of the 1.1 thing too but did not see in the BIOS a plave to change that. I will check again.

Thanks hanccocka,
That is good to know. I am going to go on site and see if the USB setting in bios needs to be changed in order to make it faster...but if not, it's good to know that slow boot won't hamper ESXI's performance.
