4-Port SuperSpeed+ USB 3.1 Gen 2 PCIe Express® Card with Dual 10Gb Controller!

Featuring two 10Gbps USB 3.1 Gen 2 controllers and four USB-C ports, the Allegro USB-C 4-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 Power
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 3.1 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 four ports support simultaneous 300 MB/s transfers!

No Auxiliary Power Required
Ordinary USB-C cards need a separate power plug connection. Sonnet’s 4-port USB-C card gets the power required to operate connected drives from the slot it’s installed in. This enables you to install the Sonnet card in any compatible computer or Thunderbolt expansion chassis regardless of it having extra power connectors available.

Independent, Per-Port Power Regulation
Ordinary USB-C cards can deliver poor power regulation, allowing a connected drive to be forced off (auto-disconnected) when an additional drive is connected or disconnected. The Allegro card protects each port from power glitches on adjacent ports, preventing auto-disconnects of already-connected drives.

Resettable Fuses
Unlike ordinary USB-C cards, the Allegro card 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.

Optimized for Thunderbolt
Got a Thunderbolt connection, but no PCIe slot? The Allegro USB-C 4-Port PCIe card is ideal for use in Sonnet’s Thunderbolt 2 and Thunderbolt 3 to PCIe card expansion systems, including Echo Express™ and xMac™ desktop and rackmount chassis. Now you can add four SuperSpeed+ USB-C ports to your computer without expansion card slots.

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 2 or Thunderbolt 3 to PCIe card expansion chassis is a great way to inexpensively add four SuperSpeed+ USB-C ports to your computer.

Broad Device Support, Easy Installation
The Allegro USB-C 4-Port PCIe card features hot-pluggable and hot-swappable device connection support with automatic device configuration, and works with all USB-IF compliant USB peripherals. This full-height Sonnet card installs easily into any PCIe x4 (mechanical) or larger slot.
