0 USB 3.1 standards released a year and a half later, the product has finally begun to launch the.TechReport has also got a new ASUS, made a simple test. USB 3.1 performance: it can not be more cool! This is a USB 3.1 test sample of ASUS and co development, equipped with a USB 3.1 Type-C interface and a micro-USB interface for data transmission and power supply, respectively, but to the retail product, a USB 3.1 should be able to get the data and power. USB 3.1 performance: it can not be more cool! The interior is the two Samsung 250GBmSATA EVO 840 RAID solid state hard drive to achieve the highest performance, which is conducive to breaking the limits of 6Gbps SATA. Of course, the better use of M.2. PCI-E USB 3.1 performance: it can not be more cool! USB 3.1 performance: it can not be more cool! The motherboard is ASUS's Z97-A/USB 3.1, provides two USB 3.1 Type-A interface, can be down compatible with 3.0/2.x USB, but can not be inserted into the negative, there will not be 100W power supply, the highest 10W. USB 3.1 master with the ASM1142, the bus channel is two PCI-E 2, you can also use a PCI-E 3, the total bandwidth is 10Gbps. The theory of USB 3.1 is the highest speed of 10Gbps, but there are two interfaces, so it is shared, and because of the limitations of PCI-E 2, the actual maximum available bandwidth is only 1GB/s. Due to the time limit, coupled with ASUS does not support TRIM and security erase, so only measured the CrystalDiskMark, while the USB 3.1 Turbo to open the accelerated mode (UAS protocol). USB 3.1 performance: it can not be more cool! Continuous read and write speed can be higher than USB 3 up to 75-78%, from less than 450MB/s to 800MB/s. USB 3.1 performance: it can not be more cool! 4K random write speed soared nearly two times, close to 80MB/s, but the random read general, only to improve the 37%. At present, the motherboard USB 3.1, data lines are already on sale, for example 3.1 tested this Z97-A/USB, American Newegg asking price $159.99, and Z97-PRO (Wi Fi AC) / USB 3.1, Z97-Deluxe/USB 3.1, but unfortunately, there is no USB 3.1 U disk, hard disk. The following is a known USB 3.1 device 0
