I've used all types of USB sticks and some are more compatible than others. If you just want to transfer files, any old key will do. However, I need a key to install on the OS and this one fits. I have installed bootable versions of Centos, Ubuntu and FreeDOS on these keys and they continue to work. I have used server maintenance setups and there is plenty of room on the dongle for the OS, updates and firmware needed to complain about my machines. I highly recommend these keys.
