Review: Better Than the Cheaper Competitor Cards - First I looked on the internet for reviews of different cards, and Allegro was at the top of the list. Do they require drivers or electrical hookups in the computer, etc, in order to function properly--no, Allegro doesn't. The important question for me is: can you really use 4 USB ports at one time with this card? Based on my experience (I have purchased 3 USB C 2 port cards, and 1 USB 4 port 3.2 card), the Allegro card is plug and play and doesn't require a driver or electrical cable hookup. And the card works properly: In one of my computers (HP z2 G9) I have two cards installed: USB C and USB 3.2 and there is no problem. Be careful of buying the cheapo cards! Review: Previous USB Card dropped connections to external drives on big file transfers, this doesn't - Working GREAT without incident on a 2012 Mac Pro 5,1 tower modified for heavy 3D workflows with no dropped connections so far for two external drives. If anything changes, I will file a follow-up report ## Features - Adds four USB 3.2 ports to your Mac Pro with PCIe slots, Windows PC, or Thunderbolt-to-PCIe card expansion chassis; transfers data up to 10x faster than over USB 2.0 connections - Supports USB 3.2 bus-powered hard drives, SSDs, DVDs & Blu-ray devices with up to 2.0A per port - Supports USB 3.2 charging port handshake, and will simultaneously synch and charge iPads and other devices that support USB 3.2 charging at 1.5A per device - Mac, Windows 11+, and Linux Compatible ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00GRGCV2G | | Best Sellers Rank | #68 in Internal USB Port Cards | | Brand | Sonnet | | Built-In Media | USB adapter | | Compatible Devices | Mac Pro, Windows, Linux, Thunderbolt Expansion Systems | | Customer Reviews | 4.6 out of 5 stars 515 Reviews | | Global Trade Identification Number | 00732311009440, 07426800095016 | | Hardware Interface | PCI, USB 3.2 Gen 1 | | Manufacturer | SONNETTECH | | Mfr Part Number | USB3-4PM-E | | Model Number | USB3-4PM-E | | Operating System | Windows 11 | | Style | Classic | | Style Name | Classic | | UPC | 801947293322 732311009440 804067727326 809394595754 808113093205 804904235502 | | Unit Count | 4 Count | | Warranty Description | 1 year warranty | ## Product Details - **Brand:** Sonnet - **Compatible Devices:** Mac Pro, Windows, Linux, Thunderbolt Expansion Systems - **Hardware Interface:** PCI, USB 3.2 Gen 1 - **Style:** Classic - **UPC:** 801947293322 732311009440 804067727326 809394595754 808113093205 804904235502 ## Images ![Sonnet Allegro USB-A 4-Port USB 3.2 Gen 1 PCIe Card Mac Windows Linux 5Gbps - Image 1](https://m.media-amazon.com/images/I/71yJRICDO9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better Than the Cheaper Competitor Cards *by R***T on February 9, 2026* First I looked on the internet for reviews of different cards, and Allegro was at the top of the list.

If anything changes, I will file a follow-up report ### ⭐⭐⭐⭐⭐ Plug & play for Mac Pro 2010 5,1 *by S***T on December 18, 2018* It works! Excellent throughput. (Tested with Blackmagic Designs disk tester on all my devices.) Mac OS High Sierra. I had a USB 3.0 4-port that fail on me (Inateck) just like a previous reviewer. The ports stopped working AND creating some conflicts on native USB ports such as external devices (SD, portable drives, etc.) preventing them to mount. Extremely happy and relieve that Sonnet was easy to install. It fit snug in the PCI-E slots and the ports line are aligned better than the former card. I was able to fully plug in Lexar UHS-II SD card reader (~250MB/s). I put it in slot 4 to avoid blocking the GPU fan, and it did not interfere with the full size hard disk mounted to drive sled above it. I can’t attest for the durability at this point. Installed yesterday. ## Frequently Bought Together - Allegro Type A USB 3.2 | 3.0 PCIe 4-Port PCIe Card (Mac and Windows Compatible) - Sonnet Echo Express SEIIIe Thunderbolt 3 Edition (3-Slot PCIe Card Expansion Chassis) - Sonnet Presto Solo 10GBASE-T Ethernet 1-Port PCIe Card [Thunderbolt 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.ec/products/13923810-sonnet-allegro-usb-a-4-port-usb-3-2-gen](https://www.desertcart.ec/products/13923810-sonnet-allegro-usb-a-4-port-usb-3-2-gen) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-16*
