The main advantages of most (if not all) main hardware wallets (such as Nano S and Trezor) is that your private-keys are isolated in that small piece of hardware. This means that whenever you connect the hardware wallet to your computer, there is not a single thing/software/virus in your computer that may sniff the private-key out of the device. You send the transaction information (amount, to which address you want to send) to the hardware device, and the transaction is signed there - with the private key - and sent back to your computer to be broadcasted.
If you just store your coins in a pen drive, whenever you connect it into your computer, the pen drive will be "mounted" in your computer, which means that it can be accessible by every process in your computer (thus, any virus can steal your coins/private-keys).
