speed is around 115 to 120MB/s so the only way the usb3 is as good is if it boots.
If it isn't supported by firmware, then the LaCie or other add-on cards will only boot at USB 2.0 speeds.
The LaCie driver has already been modded to bypass the check for LaCie peripherals. Current anecdotal tests with the hacked driver suggest that the hard drive is now the bottleneck and speeds are the same as eSATA.
