   The UAS is a newer implementation for mass storage devices, this uses a   
   SCSI based protocol instead of the Bulk-Only Transport of the USB. Main   
   benefit with UAS is higher transfer speeds from/to usb connected mass   
   storage units.   
      
   As the device you use seems to have issues with UAS (at least the Linux   
   implementation), so the option seems to be to relay on the old USB   
   functionality and the benefit for you would be something that works.   
      
   The following numbers based on tests on a Banana Pi:   
   Seq Write: ~10% slower on USB vs UAS   
   Seq Read: ~14% slower on USB vs UAS
