USB Attached SCSI Protocol (UASP) is a protocol that enables faster and more efficient data transfer between an external storage device and a computer compared to the traditional Bulk-Only Transport (BOT) protocol. UASP supports simultaneous processing of multiple commands, resulting in better utilization of the speed of USB 3.0 and higher interfaces. This feature is ideal for devices requiring high throughput, such as SSDs, and provides faster data access and transfer.
