Bought them to install Linux, multiple distros. I really only need 8GB. Not exactly $5 a piece though, it's a great value. Tests show they use the USB 3.0 specification. I need them read-only after "burning" the ISO once. Works great for me. I've actually done it really well (running Linux directly from a flash drive).
