USB 3.1 Gen 2 Type-A
Ultimate-speed 10Gbps with USB 3.1 Gen 2 onboard
With backward-compatible USB 3.1 Gen 2 Type-A™, you’ll experience ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps — twice as fast as standard USB 3.1 Gen 1.
USB 3.1 Gen 1 front-panel connector
USB 3.1 Gen 1 is right where you need it, with two super-speed headers for the front panel. Experience data-transfer speeds up to 10X faster than USB 2.0 with instant plug-and-play connectivity, and avoid back-breaking contortions in the hunt for hard-to-reach rear ports.
Speed up with onboard M.2
With x4 PCI Express® 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It’s the perfect choice for an operating system or application drive, providing fast access to data.
AMD StoreMI technology is a software utility that accelerates any drive for better system responsiveness with reduced startup and software load times. It combines SSD performance with the affordability and capacity of an HDD by automatically moving frequently accessed data to dedicated SSD storage.
