Kingston is good to go.
no offence but this doesn't mean a great deal, im sure they have many products just like sandisk do, any specific model you can recommend?
DataTraveler DT100G2 and DT Minifun have great speed and excellent performance for writing multiply files at the same time. I've got 16Gb Transcend JetFlash 330 as well, and it's absolutlely horrible for work with any OSes - installed Windows7/Ubuntu on it and it was extremely slow performance. Kingston is about 10-20 times faster in such situations.
BAMT is designed as a live cd with very minimal persistency. Therefore, it loads into memory and only writes changes to the config files, so any old stick will work. A faster one just means faster boots and faster loading the stick from your host box. Once it is running, it doesn't make any difference at all.
