Maximum USB-C Performance

Allegro Max USB-C

20Gbps 1-Port PCIe Card

Stunning USB 3.2 Gen 2x2 Performance: Add One USB-C 20Gbps Port to Computers and Thunderbolt Expansion Systems with PCIe Card Slots

Your computer’s USB ports are perfectly adequate…for connecting peripherals that don’t depend on the ultimate USB 3.2 speeds. Onboard USB ports can be underachievers — at 5Gbps or 10Gbps, they can’t support the maximum performance from many storage devices and may not provide enough power to enable them to operate. With the Sonnet Allegro™ Max USB-C 20Gbps 1-Port PCIe Card installed into a PCIe slot of your Mac® (macOS® Sonoma required), Windows® or Linux® computer, or Thunderbolt expansion system, you can upgrade to the benefits of SuperSpeed 20Gbps USB-C!

Power Advantages
Unlike many ordinary USB-C cards, the Allegro Max card has the following advantages:

• Delivers 15W of power to USB-C bus-powered devices
• Doesn’t require an auxiliary power plug connection; gets the power required to operate connected drives from the slot it’s installed in
• Features a resettable fuse, protecting both card and computer should a cable or peripheral fail; resetting a tripped fuse is simple – just shut down and restart your computer

Up to Twice as Fast as a USB 3.2 Gen 2 Card

Allegro Max USB-C 20Gbps 1-Port PCIe Card supports data transfers at up to 20Gbps, twice the speed of a USB 3.2 Gen 2 card (10Gbps) and can also deliver 15W of power to USB-C bus-powered devices.
