AMD and Intel both do not have native chipset support for SuperSpeed USB 20 Gbps, so a third party controller is necessary. This motherboard is compatible with the latest SuperSpeed USB 20 Gbps standard (USB 3.2 Gen 2×2) since ASUS went the extra mile and placed an ASMedia ASM3242 USB 3.2 2×2 host controller on the board. For that we turned to the AMD TRX40 platform and to be specific the ASUS ROG Zenith II Extreme motherboard.
To test out a ASUS U32 20G enclosure we needed a platform that supports USB 3.2 Gen 2×2. Performance Benchmarks on SuperSpeed USB 20Gbps All USB 3.2 Gen 2×2 products use the Type-C connector, but not all USB-C ports are capable of reaching 20Gbps.Ĭonfused yet? The table below will likely help clear things up.
It is able to reach this speed by using two USB 3.2 Gen 2 lanes. The newest and fastest version of USB 3.2 is called USB 3.2 Gen 2×2 (20Gbps). USB 3.1 (10Gbps) is called USB 3.2 Gen 2. USB 3.0 (5Gbps) is now called USB 3.2 Gen 1. By doing this the new USB 3.2 branding now encompasses the old USB 3.0 and 3.1 standards. The trade group USB Implementers Forum (USB-IF) renamed USB 3.1 to USB 3.2 earlier this year. Eventually it will gain broader support when pricing comes down and we expect it to become a standard feature a few years down the road. You won’t find SuperSpeed USB 20Gbps ports on mainstream motherboards though as it is currently a feature found on high-end motherboards like the ASUS Prime X299 Edition 30 ( $749.99 shipped) and the ASUS ROG Zenith II Extreme ( $849.99 shipped).
Motherboards and storage devices supporting SuperSpeed USB 20Gbps ports are just now coming to market. The ASUS U32 20G enclosure will probably be around $40 or less and boasts theoretical maximum data transfer rates of up to 20 Gbps or 2.5 GB/s. Legit Reviews managed to get our hands on an early sample of the upcoming ASUS ROG USB 3.2 Gen 2×2 (SuperSpeed USB 20Gbps) enclosure. SuperSpeed USB 20Gbps Arrives (USB 3.2 Gen 2×2)
