Consumer versions often are. We use external "non-consumer" drives
either for semi-archival storage or for transfer of full directory
structures -- more feasible with a USB 3 interface. We typically use
portable enclosures for the same quality of SATA drive that we put into
workstations, typically just below the "enterprise" quality that we use
in servers. We do not use enclosures that obtain power from the USB
port, but rather have an external power supply connected to the same
mains circuit (and safety U-ground -- USA NEMA 5-15 mains) as the
machine to which we connect to minimize earth potential differences.
Thus far, we have good luck with such drives, having no less reliability
than those in a regular computer, provided the external drive is not
subjected to impact damage. Did the post include the model and
specifications for the external drive?
