Sealed block, non-slip surface, USB Type-A box connector. For me, the most reliable option, since connectors of other standards are loosened much faster.

It has good shock protection. But with a strong fall, the data will still be damaged, the disk is of the old type. The usb port is quite fortified and not very loose.
