Allegro Pro USB-C 8-Port PCIe Card | 8-port, USB-C 10Gbps (USB 3.2 Gen 2) PCIe Card with Four USB Controllers Plus USB-C Charging for USB Peripherals

Pro Ports. Max Performance from Each One - First pro PCIe adapter card with eight external USB-C ports, four USB 3.2 controllers, and an x8 PCIe 3.0 bridge chip.

Even in computers with multiple expansion card slots, every slot is valuable-there may not be space to install two 4-port adapter cards. Sonnet's Allegro™ Pro USB-C® 8-Port PCIe Card is the first adapter card ever to feature eight high performance USB-C ports, fitting them neatly on a standard full-height PCIe card bracket. Ports are spaced to enable connection of eight cables (and even USB-C male to USB-A female adapters).

Why Sonnet? Many multi-port USB cards split a single USB controller's bandwidth among their ports, limiting performance when two or more devices are connected and operating. When installed in a computer's PCIe 3.0 or 4.0 slot, Sonnet's card provides full 10Gbps bandwidth to every one of its eight ports, ensuring maximum performance from each one.

The Most Capable 10Gbps USB Card - USB SSD Nirvana

Equipped with NVMe SSDs, the fastest USB 3.2 Gen 2 drives available can transfer data at incredible speeds. Chances are your computer has few ports capable of supporting their full performance. Upgrade your workflow in a major way by installing Sonnet's Allegro Pro USB-C 8-Port PCIe Card in your Mac Pro®, Windows, or Linux computer; or Echo™ III Thunderbolt™ to PCIe card expansion system to support up to eight NVMe USB drives at maximum performance*, no power adapters needed.

High Speed Simultaneous Transfers - 10Gbps from Every Port!

Many multi-port USB cards are simple hubs that split a single USB controller's bandwidth between all its ports, which limits their performance when two or more devices are connected and operating. When installed in a computer's PCIe 3.0 or 4.0 slot, the Allegro Pro USB-C 8-Port PCIe Card supports eight simultaneous 10Gbps transfers. It is ideal for transferring data from multiple drives to the computer (and from drive to drive)-data transfers from a single USB 3.2 NVMe SSD device at up to 1000 MB/s. Compared to using a USB 3.1 Gen 1 or USB 3.0 adapter card, transfers complete in half the time!

Built to Perform - Advanced Bandwidth Management Architecture

With its advanced architecture, the Allegro Pro USB-C 8-Port PCIe Card can deliver full 10Gbps bandwidth to each of its ports*. This is accomplished by providing each USB controller access to two lanes of PCIe 3.0 via an x8 PCIe 3.0 bridge chip, plus by implementing advanced data traffic management to eliminate bandwidth congestion. By providing full-bandwidth PCIe bridging to four controllers and by eliminating bandwidth congestion, this Sonnet card is the highest-performing USB 3.2 Gen 2 PCIe card ever made.

Virtually Independent - Supports Four Independent Physical Connections to Virtual Machines (VMs)

The Allegro Pro USB-C 8-Port PCIe Card's four independent USB 3.2 controllers control a pair of ports each. If your VM software supports direct physical connections, then each of these four controllers can be independently attached to a separate virtual machine.
