I would recommend just getting an inexpensive USB 3.0 m.2 or sata adapter ($10) and using a spare drive you have laying around with it. Should be dramatically more reliable.
(Just be careful if you decided to use a large spinning disk, they can have higher power draw than the Pi can support, m.2 or sata SSD is the way to go here if you want simplicity)
… your nas only had 12gb of storage??
