Add Four USB-C 10 Gbps Ports |
|
Equipped with SSDs, the fastest USB 3.2 Gen 2 drives you can buy today are capable of 800 MB/s data transfers — many are bus-powered, too. But, most desktop computers (even new models) include generations-old USB interfaces that will throttle that performance and may not offer adequate power to allow bus-powered drives to operate. Break through the bottleneck — install Allegro™ USB-C 4-Port PCIe(1) card to instantly add four USB-C 10 Gbps ports to your system. Two Controllers, Four Ports Featuring two 10 Gbps USB 3.2 Gen 2 controllers and four USB-C ports, the Allegro PCIe card supports data transfers at up to twice as fast as USB 3.0 and USB 3.1 Gen 1 ports are capable. With two controllers onboard, the Allegro card speeds data transfers between connected drives, and enables your computer to load and off-load data more quickly. |

Speed and Power Unlike other 4-port USB cards (simple hubs that split a single USB controller’s bandwidth between all four ports), Sonnet’s Allegro PCIe card supports data transfers from a single USB 3.2 Gen 2 SSD RAID device at up to 800 MB/s— compared to using a USB 3.1 Gen 1 or USB 3.0 adapter card, transfers complete in half the time! Exploiting its dual controllers design, it’s possible to simultaneously transfer data to two connected drives at up to 660 MB/s each. With four drives connected, the four ports support simultaneous 300 MB/s transfers! |
Sonnet Port Power Advantages: Unlike ordinary USB-C adapter cards, Sonnet's Allegro PCIe card was designed with a focus on intelligent power delivery and management for powering attached drives through its ports. |

Easy to Access Ports Sonnet designed the Allegro USB-C 4-Port PCIe card with custom USB-C connectors that locate the ports near the center of the PCIe bracket. Unlike other cards that use standard Type-C connectors that are mounted close to the edge of the bracket, this Allegro card provides plenty of clearance for you to plug in cables. |
