Sonnet - 'Allegro USB-C 4-Port PCIE'

Sonnet - Allegro

Powerful USB 3.2 Gen 2 Performance 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(1) card in your Mac Pro®, Windows® PC, or Linux®(2) computer with PCIe slots; or Thunderbolt™ to PCIe card expansion system to support your fast USB drives at maximum performance.

at a glance • Four SuperSpeed USB-C 10Gbps Ports
• Powerful Performance with Dual USB 3.2 Gen 2 Controllers
• Powered Ports
• Broad USB Device Support & Compatibility
• Add USB 3.2 Gen 2 to Thunderbolt Expansion Systems
• Supports Hot-Swappable Device Connection

Two Controllers, Four Ports


2x faster than USB 3.0 and USB 3.1Featuring 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

4K Recording

simultaneous 300 MB/s transfersUnlike 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!

No Auxiliary Power Required


installs on any compatible systemOrdinary 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


prevents auto-disconnectsOrdinary 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 FusesUnlike 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.

Sonnet Port Power Advantages

Add USB 3.2 to Your Thunderbolt MacGot 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 Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function.

By equipping resistors with an Anti-Sulfur Design GIGABYTE gives Ultra Durable Motherboards a whole new meaning. The alloy protective layer that is shown it the image above, shows that the resistor is protected.

Broad Device SupportThe Allegro 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.
