SuperSpeed USB-C 10Gbps - Dual Controllers for Fast Drive-to-Drive Transfers USB-C Charge and Sync - Four Ports with up to 7.5W Power per Port

Powerful USB 3.2 Gen 2 Performance, Add Four USB-C 10Gbps Ports to Mac Pro and Windows Computers with PCIe Slots; and Thunderbolt to PCIe Card Expansion Systems

Equipped with SSDs, the fastest USB 3.2 Gen 2 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® 4-Port PCIe(*) card in your Mac Pro® or Windows® PC computer with PCIe slots; or Thunderbolt™ to PCIe card expansion system to support your fast USB drives at maximum performance.

Two Controllers, Four Ports
Featuring two 10Gbps USB 3.2 Gen 2 controllers and four USB-C ports, the Allegro 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 PCIe 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 four 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.

Sonnet Port Power Advantages:

Unlike ordinary USB-C adapter cards, Sonnet's Allegro PCIe card was designed with a focus on intelligent power delivery and management for powering attached drives through its ports.

No Auxiliary Power Required
Ordinary USB-C cards need a separate power plug connection. Sonnet’s Allegro 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 system 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.

Add USB 3.2 to Your Thunderbolt Mac
Got a Mac with a Thunderbolt connection, but no PCIe slot? The Allegro 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 systems.

Perfect for the Extra Slot in Your Multi-Slot Thunderbolt System
Installing an Allegro USB-C 4-Port PCIe card in a multi-slot Thunderbolt 2 or Thunderbolt 3 to PCIe card expansion system is a great way to inexpensively add four SuperSpeed USB-C 10Gbps ports to your computer.

Technical Notes

1. Product complies with USB 3.2 Gen 2 specification, which supercedes USB 3.1 Gen 2. Product package may still list USB 3.1 Gen 2.

2. The maximum Apple-supported OS for the Mac Pro 3,1 is OS X 10.11. Dosdude1 offers patchers to allow installation of newer versions of macOS for the Mac Pro 3,1. The Apple USB 3 driver in these patched newer versions will support the Allegro card. Note that performance may be limited by the Mac Pro 3,1 PCIe 1.1 slot bandwidth.

3. macOS 10.12 erroneously reports a 5Gbps connection when connected at 10Gbps.

4. Must authorize charging support kernal extension in Security and Privacy System Preferences. (Unlock, then allow.)

5. Not compatible with Thunderbolt 1 to PCIe Card Expansion Systems.

6. Cables, adapters and thumbdrives with connector overmolds > 6.5mm will not fit in the 2019 Mac Pro PCIe backplate opening.

7. The initial version with serial number starting with “A” uses the ASMedia 1142 controller. The later versions with serial number starting with “B” and above (shipping since July 2020) use the ASMedia 3142 controller.
