Allegro Pro USB 3.0 4–Port
SuperSpeed USB 3.0 Charging PCI Express 2.0 Card

Mac / PC / USB 3.0 / PCIe
Add Four SuperSpeed USB 3.0 Connections to Your System
Don't settle for less
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 USB 3.0 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 Pro USB 3.0 4–Port card to instantly add four SuperSpeed USB 3.0 ports to your system to take full advantage of today's drives' performance capabilities.
Charge your devices using USB 3.0
Sonnet specially engineered the Allegro Pro USB 3.0 4–Port card to provide extra power through its ports without the need for you to connect an auxiliary power cable. Delivering up to 10W of power per port, this Sonnet solution supports USB 3.0 bus–powered hard drives, SSDs, DVDs & Blu–ray devices without the need to connect an additional AC power adapter. The Allegro Pro USB 3.0 card also supports the USB 3.0 charging specification that enables you to simultaneously charge and sync your iPad, iPhone, or other device that supports USB 3.0 charging!
Easy installation
The Allegro Pro USB 3.0 4–Port card 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 3.0 and USB 2.0, peripherals.
Optimized for Thunderbolt
Got a Thunderbolt connection, but no PCIe slot? The Allegro Pro USB 3.0 4–Port card is ideal for use in any Thunderbolt to PCIe card expansion chassis, offering full performance wherever you install it–now you can add SuperSpeed USB 3.0 charging connections any Mac with a Thunderbolt port.

Rating: 5/5 Perfect for NAS storage arrays July 29, 2018 I have multiple Drobo boxes and wanted to access them with USB 3.0 on my MacPro 5,1. I tried a standard USB 3.0 card but the Drobos wouldn't mount. This powered port card works perfectly. I also like that it doesn't need any special drivers. I am running OSX 10.13.

Rating: 5/5 Very good quality ! December 10, 2017 This card is very well built with very good components. It was harder to install than I expected. The explanation-video was not too good... I had to improvise a lot to install it correctly. Finally, I managed, by myself... to really install it properly.

Rating: 5/5 This USB 3 was what doctor ordered June 11, 2017 I used this to replaced a older USB 3 drive. The older one disconnected my external drives when the computer went to sleep and it would reconnect. This one works flawlessly. It initially disconnected the external drive when the computer went to sleep but would reconnect on wake. Now it doesn't disconnect at all. Maybe there was a firmware update. Subway, I love this connector, highly recommended. Sonnet Technologies Allegro Pro USB 3.0 4-Port SuperSpeed USB 3.0 Charging PCI Express 2.0 Card is just what the doctor ordered. I used this on my Mac pro to give me 4 extra USB 3 ports. I connected a 8 TB external WD drive to it and it is super fast. If you have a 2010 Mac pro and need extra ports.

Rating: 5/5 Great USB 3 add on card for the last Aluminum MacPro January 11, 2017 This card is being used to replace a much older USB 3 add on card installed in the last Aluminum MacPro. It works great and gives the advantage of USB 3's faster speeds that Firewire 400 or 800. Very good price and offering 4 separate channels (like a Switch rather than a Hub) it has much faster throughput than the old one's did.
