SuperSpeed USB-C 10Gbps - Dual Controllers for Fast Drive-to-Drive Transfers USB-C Charge and Sync Four Ports with up to 7.5W Power per Port Unlike other 4-port USB cards (simple hubs that split a single USB controller’s bandwidth between all four ports), Sonnet’s Allegro USB-C 4-Port PCIe computer card supports data transfers from a single USB 3.2 Gen 2 SSD RAID device at up to 900 MB/s— transfers complete in half the time! Speed and Power Equipped with SSDs, the fastest 3.1 Gen 2 USB drives you can buy today are capable of 900 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 Sonnet’s Allegro USB-C 4-Port PCIe card in your Mac Pro tower, or Windows PC, with PCIe slots to support your fast USB drives at maximum performance. No Auxiliary Power Required. USB3C 4-Port PCIe Protected Power Delivery Independent power regulation isolates each port to prevent cross-coupled power glitches that may cause accidental disconnects; resettable device overcurrent fuses protect the card and computer, and may be reset by a simple shutdown SuperSpeed+ USB x4—Adds four 10Gbps USB-C ports to your Mac Pro, or Windows PC computer with PCIe slots; or Thunderbolt to PCIe card expansion system Dual USB 3.1 Gen 2 Controllers—Support data transfers at up to twice as fast as USB 3.0 and USB 3.1 Gen 1; speed data transfers between connected drives Powered Ports—Supports USB-C bus-powered SSD, or SSD RAID, with 7.5W per port Broad USB Device Support & Compatibility—Supports storage, hubs, and other USB-IF compliant USB devices Does Not Support Thunderbolt Peripherals Supports Hot-Swappable Device Connection—Plug in and disconnect peripherals without shutting off your computer 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. Perfect for the Extra Slot in Your Multi-Slot Thunderbolt Chassis Installing an Allegro USB-C 4-Port PCIe card in a multi-slot Thunderbolt to PCIe card expansion chassis is a great way to inexpensively add four SuperSpeed+ USB-C ports to your computer.
