Sonnet USB3-Pro-4P10-E Allegro Pro USB 3.0 PCIE Card

Sonnet USB3-Pro-4P10-E Allegro Pro USB 3.0 PCIE Card

Powerful USB 3.2 Gen 2 Performance: Add Four USB-A 10Gbps Ports to Computers and Thunderbolt Expansion Systems with PCIe Slots

Current SSD-based USB 3.2 Gen 2 drives can transfer data at 800 MB/s, and many are bus-powered. But, most desktop computers feature old-generation USB interfaces that can’t support the performance and power requirement to enable modern bus-powered drives to function. With a Sonnet Allegro Pro Type A USB 3.2 PCIe card installed into the PCIe slot of  your Mac Pro®, Windows®, or Linux® computer, or Thunderbolt Expansion System, you'll have more than enough bandwidth to support super-fast USB drives at maximum performance.


Power Advantages

Unlike ordinary USB-A cards, Sonnet's Allegro has the following advantages:

  • Delivers 7.5W of power per USB port for USB-powered devices
  • Doesn't require separate power plug connection; gets the power required to operate connected drives from the slot it’s installed in
  • Independent, per-port power regulation protects each port from glitches on adjacent ports, preventing auto-disconnects of already-connected drives
  • Features a resettable fuse on each port, protecting both card and computer should a cable or peripheral fail; resetting a tripped fuse is simple—just shut down and restart your computer

Allegro Pro Type A USB 3.2 PCIe: Two Gen 2 Controllers, Four USB-A Ports

Featuring two 10Gbps 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. Connected to a single USB 3.2 Gen 2 SSD RAID device, the Allegro supports data transfers up to 800 MB/s—transfers complete in half the time 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!
