ASUS announced USB 3.0 Boost, it adds UAS Protocol support to enable up to 170 percent faster data transfers.
ASUS USB 3.0 Boost adds new UAS Protocol support for improved data transfer speeds and lower CPU utilization, offering compliance with a protocol recently introduced by the USB-IF to augment data connectivity. USB 3.0 Boost enables native UASP (USB Attached SCSI Protocol) support, as well as full backward compatibility with the traditional Bulk-Only Transport (BOT) protocol. Auto detection of connected devices ensures the most suitable protocol available is used, resulting in 170% faster data speeds compared to original USB 3.0 speeds. A dedicated USB 3.0 Turbo Mode accelerates the performance of all USB devices for an overall increase in data transfer speeds.

The benefits of UASP implementation
Initial USB 3.0 integration retained the BOT protocol of USB 2.0, in effect limiting potential transfer speeds and bandwidth even though USB 3.0 has been designed to work up to ten times faster than USB 2.0. As soon as UASP became available, ASUS made sure to begin its deployment. Compared to traditional protocols, UASP offers maximized bandwidth utilization, and can handle multiple data transfer requests at once, unlike the slower queue system of B OT, which only provides single-task command. Because of this, USB 3.0 connections working in UASP mode result in higher data speeds and lower CPU utilization. UASP clears data queues faster, translating into a smoother-operating PC.

USB 3.0 Boost goes beyond the specs
In addition to UASP compatibility, USB 3.0 Boost from ASUS includes three modes that cater to different user needs and profiles for increased flexibility. UASP Mode maximizes usage of the new protocol, Turbo Mode accelerates all USB devices, and Normal Mode operates at original USB 3.0 speeds to guarantee the best compatibility with all devices. Instant auto detection determines the best mode for any connected USB device on USB 3.0 ports, switching between UASP Mode and Turbo Mode as needed. All told, USB 3.0 Boost can accelerate data speeds by 170% with UASP mode compared to original USB 3.0 speeds. To make usage more accessible, USB 3.0 Boost comes with a friendly and intuitive interface exclusive to ASUS motherboards, helping users make the most of its full potential.

ASUS USB 3.0 Boost exceeds USB 3.0 performance
Compared to traditional protocols, UASP offers a significant speed boost, increasing data transfer expediency. UASP is also a much more efficient protocol in terms of data spread. ASUS USB 3.0 Boost makes the most of the advantages of UASP and traditional architectures, decreasing latency between the motherboard and connected devices considerably. It is the result of extensive research and prompt implementation in a wide range of new motherboard products.
