For all who are interested:
Today i tried to Boot Proxmox-2.3 from a external USB3-SSD, but it did not work.
In search of a solution, I found: http://evilshit.wordpress.com/2012/0...ot-that-stick/
Summary:
add the following line to the "/etc/initramfs-tools/modules"
xhci_hcd
and create a new initrd with
update-initramfs -u
Add "rootdelay=10" to "/boot/grub.cfg" as Kernel Boot-Parameter.
...and now it works :)

"FSYNCS" and "AVERAGE SEEK TIME" are much better on USB3 than on USB2, but "BUFFERED READS" on USB3 are lower than on USB2 !?
