Since this thread is on the topic, I'll ask my question here rather than starting up a new one.

I'm also planning on booting BT5 from a USB flash, but I am unsure as to whether I should boot it from a live USB flash or simply do a full install of BT5 onto the flash drive (provided that the drive is large enough, e.g., 32GB+). Am I correct to believe that I have both the option of putting the ISO file onto the USB (via programs like Lili, uNetBootin, Linux PenDrive Creator, etc...) and running BT5 directly from the ISO AND the option to fully install BT5 onto the USB drive? And if yes, which option should I choose? Will there be a speed advantage if I fully install BT5 as opposed to running it off an ISO?
