[M] Silicon Power Mobile C07 USB 3.2 Gen1 USB Type-C 256GB Flash Drive Review
 

The Marvel C07 USB-C 3.2 Gen1 offers entry-level performance for the supported bus, but it should be fine for most mainstream applications, since it does not heat up at all. We can use it to transfer data from mobile devices supporting OTG as well and can be dedicated as a secondary backup device (besides cloud) when moving large quantities of data; in this case we would recommend going for either the 128 or 256GB variant.
