Newly-introduced ASUS technology combines the world's first complete USB 3.0 UASP support for 170% faster data transfers

ASUS USB 3.0 Boost Creates Total USB 3.0 Performance Enhancement

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 BOT, 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.

About ASUS USB 3.0 Boost

USB 3.0 has become the standard high-performance data transfer technology for PCs, however, there is still room for improvement! New USB 3.0 Boost is an exclusive ASUS innovation that goes beyond original USB 3.0 speeds, delivering the latest UAS Protocol (UASP) on ASUS motherboards, and giving consumers up to 170 % faster data transfer performance as well as an accelerated Turbo Mode that supports all USB devices with the traditional BOT (Bulk Only Transfer) protocol.

▪ What is UASP?
The popular USB 3.0 format is limited by BOT specifications, originally designed for the slower USB 2.0. The USB International Forum has introduced UASP (USB Attached SCSI Protocol) recently to offer more optimized transfers for products with USB 3.0. The main differences between UASP and BOT are multiple simultaneous commands on UASP, while BOT can only handle one command at once. This reduces wait times, maximizes bandwidth utilization, and therefore enables faster and more efficient transfers. UASP also helps lower CPU utilization.

ASUS exclusive USB 3.0 Boost kicks it up a notch
Exclusive ASUS technology takes USB 3.0 to a whole new level of greater speed and efficiency. With USB 3.0 Boost, users get the flexibility of multiple modes that work great no matter which device is connected:
UASP Mode: dedicated to new UASP devices for max performance with the latest specifications.
Turbo Mode: accelerates USB BOT devices, increasing their transfer speeds.
Normal Mode: guarantees complete compatibility with all USB devices.
This three-mode design caters to different user needs for complete flexibility. Instant auto detection means USB 3.0 Boost recognizes the best protocol for every connected device, ensuring optimized output with no need to query the user for settings. As such, using USB 3.0 Boost and making the most of its advantages is easy for everyone, regardless of technical experience. Since UASP Mode and Turbo Mode engage instantly, the best performance is assured hassle-free. Meanwhile, Normal Mode allows users to switch acceleration off when it’s not needed.
How ASUS USB 3.0 Boost Turbo Mode improves device transfer speeds
Standard USB 3.0 transfer speeds dramatically accelerate thanks to exclusive ASUS technology, which intelligently adjusts data transfer commands into large batches and sends them out at once, significantly decreasing latency between the motherboard and connected devices. Turbo Mode accelerates all USB devices for faster and more efficient transfers.
