USB Attached SCSI (UAS or UASP) is a computer protocol used to move data to and from USB storage devices such as hard drives (HDDs), solid-state drives (SSDs), and thumb drives. UAS depends on the USB protocol, and uses the standard SCSI command set. Use of UAS generally provides faster transfers compared to the older USB Mass Storage Bulk-Only Transport (BOT) drivers.
You want UASP enabled on your USB ports because it uses the SCSI protocal which has UNMAP, which is a feature similar to TRIM, which helps the health and performance of the SSD.
Please check with your System manufacturer or Motherboard manufacturer for UASP support.
