Transfer Files From 20Gbps USB-C SSDs at Maximum Speed
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 of USB 3.2 Gen 2×2 storage devices — up to 2000 MB/s — and may not provide enough power to enable them to operate. With Sonnet Allegro™ Max USB-C 20Gbps 1-Port PCIe Cardinstalled into a PCIe® card slot of your Mac Pro® (requires macOS® Sonoma 14.4 or later), Windows or Linux computer, you can upgrade to the benefits of SuperSpeed 20Gbps USB-C®!

The Sonnet Advantage
Transfer Files at Up to 2000 MB/s!
Easy Installation. Simple Operation.
There’s no software for you to install — just insert Allegro Max USB-C 20Gbps 1-Port PCIe Card into a x4 PCIe slot (both low-profile and full-height mounting brackets are included) — and then turn on your computer for an instant upgrade.
The Sonnet card features hot-pluggable and hot-swappable device connection support with automatic device configuration and works with all USB-IF compliant USB peripherals.

Easy to Access Port
Sonnet designed Allegro Max card with a custom USB-C connector that locates the port near the center of the PCIe bracket. Unlike other cards that use standard Type-C connectors that are mounted close to the edge of the bracket, this Allegro card provides plenty of clearance for you to plug in and fully seat cables.
