I would recommend editing your fstab and use the USB drive's UUID to mount it to a consistent location. That way, even if you reboot or disconnect the drive and the reconnect it to, say, a different USB port, it will always mount to the same mountpoint.
See this page from the arch wiki for more info.
If you don't want it, I'll take it off your hands. I have a rack designed for that kind of hardware and all of the infrastructure to fully support it.
