To be condemned to USB 2 ports in this day and age is pure torture. Luckily the good people at Sonnet have come to the rescue with this 4-port USB 3.1 gen2 PCIe card. Installing it was literally plug and play.Now I can attach any modern, high-speed, peripherals like an external USB-C (3.1 gen2) M.2 SSD drive and get very decent speeds. The screen grabs below are from a Sabrent 1TB M.2 NVMe inside a Sabrent enclosure. This PCIe card by Sonnet has completely transformed my computer's abilities. Very impressed. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great PnP solution for Macs *by P***S on Reviewed in the United Kingdom on 15 October 2019* Great. Has given my Mac Pro 5.1 a new lease of life. Installed with zero problems, no drivers and no extra power cables to hook up. The whole process took about 3 minutes. ### ⭐⭐⭐ 3.0 out of 5 stars Now on the 3rd card in a year *by M***N on Reviewed in the United Kingdom on 22 December 2020* Now purchased my third card as the previous two failed; the first within a week, the second in 49 weeks. Two of the four ports fail to communicate or recognise a USB device when inserted. When working the card works great on my MacPro. ## Frequently Bought Together - Sonnet Allegro USB-C 4-Port PCIe Card - Sonnet Allegro Pro USB 3.2 Type A PCIe Card (Four SuperSpeed 10Gbps USB Connectors) - Allegro Type A USB 3.2 | 3.0 PCIe 4-Port PCIe Card (Mac and Windows Compatible) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/115025039-sonnet-allegro-usb-c-4-port-pcie-card-thunderbolt-compatible](https://www.desertcart.sn/products/115025039-sonnet-allegro-usb-c-4-port-pcie-card-thunderbolt-compatible) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
