USB-A 10 Gbps • Dual Controllers for Fast Drive-to-Drive Transfers |
|
Add Four USB-A 10 Gbps Ports |
|
The fastest SSD-based USB 3.2 Gen 2 drives now available can transfer data at 800 MB/s — many are bus-powered, too. But, most desktop computers (including many new models) feature old-generation USB interfaces that can’t support that performance, and may not provide enough power to enable those bus-powered drives to function. Break through the bottleneck — install Sonnet’s Allegro Pro Type-A USB 3.2 PCIe(1) to instantly add four USB-A 10 Gbps ports to your system. Two Gen 2 Controllers, Four USB-A Ports Featuring two 10 Gbps USB 3.2 Gen 2 controllers and four USB-A ports, the Allegro PCIe card supports the fastest USB drives available, yet provides the most common connection type for peripheral devices. |
Key Features Four SuperSpeed USB-A 10 Gbps Ports — Adds four USB-A 10 Gbps ports to your Mac, Windows, or Linux computer or Thunderbolt expansion system with PCIe slots Powerful Performance with Dual USB 3.2 Gen 2 Controllers — Support data transfers at up to twice as fast as USB 3.0 and USB 3.1 Gen 1, and boost data transfer speeds between connected drives Powered Port — Supports USB bus-powered SSD, SSD RAID, and hard drive devices with up to 7.5W power per port Supports Charge & Sync — Supports USB 3.0 charging port handshake, and will simultaneously sync and charge iPads and other devices that support USB 3.0 charging at 1.5A per device 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 Add USB 3 Thunderbolt Expansion Systems — Add four SuperSpeed USB-A 10 Gbps ports to Thunderbolt expansion systems Easy Installation — Quick and easy user installation into any available PCIe slot Broad USB Device Support & Compatibility — Supports storage, hubs, and other USB-IF compliant USB devices |
The Speed and Power Connected to a single USB 3.2 Gen 2 SSD RAID device, Sonnet’s Allegro PCIe card supports data transfers up to 800 MB/s—transfers complete in half the time(2) compared with using a USB 3.1 Gen 1 or USB 3.0 adapter card. Made possible through the use of dual controllers, with two connected drives, each port supports simultaneous 660 MB/s transfers. With four drives connected, each port supports simultaneous 300 MB/s transfers! |
