2x the Performance of USB 3.0 and USB 3.1 Gen1 ConnectionsEquipped with SSDs, the fastest 3.2 Gen 2 USB 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 Sonnet’s Allegro™ USB-C 8-Port PCIe card in your Mac Pro® tower, Windows® PC,
 or Linux(1) computer with PCIe slots; or Thunderbolt™ to PCIe card expansion system to support 
your fast USB drives at maximum performance.
Two Controllers, Four PortsFeaturing two 10Gbps USB 3.2 Gen 2 controllers and eight USB-C ports, the Allegro USB-C 8-Port 
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 PowerUnlike other 8-port USB cards (simple hubs that split a single USB controller’s bandwidth between 
all four ports), Sonnet’s Allegro USB-C 8-Port PCIe computer 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 eight ports support simultaneous 300 MB/s transfers!
The Allegro card provides 7.5W of power through each of its ports, supporting USB bus-powered hard 
drives, and SSDs without the need to connect an additional AC power adapter.
