However, most external drives are meant to be low-use storage drives, so using them as a primary or high-use will cause them to fail faster than normal, but that's no different than using any other storage drive.
edit: I will say that external drives do not cool down well in their cheap cases, and the large heat build up will cause it to fail much faster if you're running games off of it.
and 5400 rpm =slow ,even if usb 3 interface speed is in theory up to it
greens are for storage only, they lack perfomance
they also stop after few minutes of inactivity in order to save energy, so frequent use means more start/stop circles=higher possibility of mechanical failure
and usb, come on get serious
