However, when I tested using the UT2's built-in hotspot, I was able to take down an average write speed of 60 MB/s and 78 MB/s read. If you want the fastest possible speeds, you'll want to transfer files via USB Type-C, which provides an average write speed of 298 MB/s and a read speed of 317 MB/s. Note that while there is a built-in UPS battery, it doesn't provide the best lifespan. On average, I was able to get about an hour to an hour and a half out of the built-in battery. However, thanks to the wide connection options, I could keep the UT2 going while out in the field by connecting it to a power bank.
