Computers with Allegro Type A USB 3.2 PCIe 4-Port Cards
SuperSpeed USB-A 5Gbps • USB Charge & Sync • Four Ports with up to 2.0A Power per Port

Speedy USB 3.2 Gen 1 Performance
Add the Speed of USB 3.2 Gen 1 Ports to Mac Pro, Windows, and Linux Computers with PCIe Slots; and Thunderbolt to PCIe Card Expansion Systems

Up to 10x the Performance of USB 2.0Upgrade to SuperSpeed Performance

Your computer’s USB 2.0 ports are perfectly adequate for connecting mice, keyboards, and printers, but if you need to connect external storage drives, USB 2.0 ports are underpowered in more ways than one—limiting data transfer speeds to around 25–30 MB/s, they can hardly be called “high performance”. Most drives available today include faster USB interfaces and offer significantly better performance than USB 2.0-equipped drives. Though you can connect them to your computer’s USB 2.0 ports, their performance would be reduced by as much as 85 percent! Don’t settle for slow performance—install a Sonnet Allegro Type-A USB 3.2 PCIe 4-Port(1) card to instantly add four SuperSpeed USB 5Gbps ports to your system to take full advantage of today’s drives’ performance capabilities.

PCIe Interface
The Allegro features a PCIe 2.0 bus interface to take advantage of your computer’s fast expansion card slots. This card installs easily into any PCI Express® (PCIe) slot that supports a full-height card, features hot-pluggable and hot-swappable device connection support with automatic device configuration, and works with all USB-IF compliant USB peripherals.

Technical Notes

  1. Product name and/or description updated to reflect current USB naming conventions:

    USB 3.2 Gen 2 = USB 3.1 Gen 2
    USB 3.2 Gen 1 = USB 3.0
  2. USB 3.0 devices require USB 3.0 cables to support USB 3.0 (SuperSpeed) transfer speeds (up to 5 Gb/s). Use of USB 2.0 cables between USB 3.0 devices and Allegro USB 3.0 4-Port is supported, but data transfers are limited to USB 2.0 speeds (up to 480 Mb/s).
