Featuring dual USB 3.2 Gen 2 controllers and independent per-port power delivery, it supports multiple high-speed devices simultaneously without bandwidth or power issues. Designed for professional workflows, it offers plug-and-play installation, robust build quality, and a 2-year warranty with lifetime support. ## Description The fastest SSD-based USB 3.2 Gen 2 drives now available can transfer data at 800 MB/s — many are bus-powered, too. But most desktop computers (including many new models) feature old-generation USB interfaces that can’t support that performance, and may not provide enough power to enable those bus-powered drives to function. Break through the bottleneck — install Sonnet’s Allegro Pro Type-A USB 3.2 PCIe(1) card in your Mac Pro tower, Windows PC, or Linux computer with PCIe slots, or Thunderbolt to PCIe card expansion system to support your fast USB drives at maximum performance. Review: Notwendig bei mehreren USB Kameras - Funktioniert ohne abzustuerzen, Braucht aber einen Reboot nach dem USB Geraete angeschlossen wurden. Review: Professional-Grade USB Expansion - The Sonnet Allegro Pro is a seriously impressive USB expansion card. What makes this card special is its architecture: the four USB 3.2 ports are split across two independent channels, which means you can run multiple high-speed devices at the same time without them fighting for bandwidth. Copying data from one port group to the other is incredibly fast and consistent — it feels like having two separate USB controllers in one card. In real-world use, this makes a huge difference. I regularly connect multiple SSDs, card readers, and capture devices at once, and performance stays stable instead of collapsing the moment you plug in a second device. Transfers between devices on different channels are especially quick, which is exactly what you want in a professional workflow. Build quality is excellent, as you’d expect from Sonnet. It installs cleanly, is instantly recognized by the system, and just works without drivers or fiddling. No glitches, no disconnects, no weird behavior. If you need serious USB performance in a desktop or workstation, this card is on a completely different level from cheap multi-port USB cards. It’s built for real work, and it shows. Five stars. ## Features - Adds four USB-A 10Gbps ports to Mac Pro, Windows, and Linux computers with PCIe slots, and Thunderbolt to PCIe card expansion systems - Dual USB 3.2 Gen 2 Controllers support data transfer speeds up to twice as fast as USB 3 Gen 1 and 20x faster than USB 2.0 - Protected Power Delivery – Independent per-port power regulation isolates each port to prevent cross-coupled power glitches that may cause accidental disconnects - Supports USB bus-powered SSD or SSD RAID with up to 7.5W per port - Includes 2-year product warranty and free lifetime customer technical support ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07LG5TS6H | | Brand | Sonnet | | Built-In Media | • Allegro Pro USB 3.1 PCIe adapter card • Documentation | | Compatible Devices | Mac Pro, Windows, Linux, Thunderbolt Expansion Systems | | Compatible devices | Mac Pro, Windows, Linux, Thunderbolt Expansion Systems | | Customer Reviews | 4.4 out of 5 stars 172 Reviews | | Global Trade Identification Number | 00732311012631 | | Hardware Interface | USB 3.2 Gen 1 | | Hardware interface | USB 3.2 Gen 1 | | Item Type Name | Adaptor. | | Item Weight | 5 Grams | | Item weight | 5 Grams | | Manufacturer | SONNET TECHNOLOGIES | | Mfr Part Number | USB3-PRO-4P10-E | | Model Number | USB3-PRO-4P10-E | | Operating System | Linux,Windows | | Style | USB3-PRO-4P10-E | | Style Name | USB3-PRO-4P10-E | | UPC | 732311012631 | | Unit Count | 4 Count | ## Product Details - **Brand:** Sonnet - **Compatible Devices:** Personal Computer - **Hardware Interface:** USB 3.2 Gen 1 - **Item Weight:** 5 g - **Style:** USB3-PRO-4P10-E ## Images ![Allegro Pro USB 3.1 PCIe Card with 4x 10Gb charging ports - Thunderbolt compatible - Image 1](https://m.media-amazon.com/images/I/71j0GT+zUvL.jpg) ## Questions & Answers **Q: Does sonnet have a history of updating drivers for these cards when MacOS updates? I bought 2 other cards and drivers were never updated for new OS.** A: No drivers are needed in current versions. The drivers are part of the OS. **Q: Is anyone using this with the mac built in bluetooth without interference in El Capitan? Other cards interfere with built in bluetooth. Mac 5.1** A: Using this card with 10.11.6 on a MacPro 5,1, and there's a bit of interference on my bluetooth mouse when I write a lot of data to my external HDs through this card. I tried two different PCI-e slots, and I'm still having problems with my mouse disconnecting, and jumping after installing the card. **Q: Does this come with the 5 year manufacturer's warranty?** A: UPDATE: I e-mailed Sonnet Jan. 24, 2017, at 1:30 am PST about this issue. Alexander wrote back and said that the Pro version definitely has a 5-year warranty, and he asked his web team to fix their website to include it on their 5-year warranty page. That was awesome!---------------------According to their website (Tech Specs tab): http://www.sonnettech.com/product/allegroprousb3pcie.html it has a 5-year warranty on the Pro version. **Q: Are there any usb 3.2 devices on the market than can connect by a usb type a cable? i thought that type a was limited to usb 2.** A: Type A cable will support 10Gb USB 3.2 connection. The cable must be rated at 10Gb. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Notwendig bei mehreren USB Kameras *by A***M on 16 July 2022* Funktioniert ohne abzustuerzen, Braucht aber einen Reboot nach dem USB Geraete angeschlossen wurden. ### ⭐⭐⭐⭐⭐ Professional-Grade USB Expansion *by D***C on 9 January 2026* The Sonnet Allegro Pro is a seriously impressive USB expansion card.
