Product Highlights
  • 2x External Ports
  • Supports up to 127 Devices
  • Supports Hot-plugging & Hot-swapping
  • Mac and Windows Compatibility

The 2-Port Allegro USB 3.0 PCI Express Controller Card from Sonnet is based on the new USB 3.0 standard that offers up to 10 times the performance of the decade-old USB 2.0 interface. A single hard drive with a USB 3.0 interface is capable of transferring data at up to 125 MB/s, while SSDs are capable of even faster transfers. You can install an Allegro USB 3.0 PCIe card into your computer to exploit the full performance potential of these fast drives.

The Sonnet's Allegro USB 3.0 PCIe features a PCIe 2.0 bus interface to take advantage of your computer's fast expansion card slots. Each of this card's ports supports bus-powered storage devices (devices that work without a separate power supply). The Allegro USB 3.0 card also supports hot-swappable storage connections.

Simple way to add two SuperSpeed USB 3.0 ports to a Mac Pro or desktop PC with PCI Express 2.0 slots
Transfers data 10 times faster than USB 2.0 connections

    I installed this on my Mid 2010 Mac Pro Desktop.

    I have a heap of HDD's and enclosures with the affordable USB 3.0 (over thunderbolt / firewire). And I wanted to unleash faster read / write speeds as MAC dont do USB3.0. I bought the LaCie PCIe 3.0 USB card, and what a fail that was - no device support for any non-LaCie device!!! (MAC ONLY)

    This card works with my USB 3.0 Enclosures but it wasnt straight forward plug and play.
    NOTE: On Mac Pro's 08-10 only install on PCIe Ports 3 or 4, and download the drivers from Sonnet's site.

    Also it states USB 3.0 powered hubs work, but the D-Link USB 3.0 Powered Hub is a no show on my Mac.

    Also Card Readers like the Trancend 3.0 don not work either. It's noted that the Sonnet Card Reader will work at 3.0 speeds..

    Overall its better than what I had before, if you need USB 3 on a MAC for 2 HHD's or Enclosures, this is the one to get.

    As it turns out, this card will not work after your MacPro has gone to sleep unless the device attached to the USB 3.0 card has its own power. Sonnet's suggestion was that I not let my computer go to sleep! Since my computer asleep uses 15 w/hour and not asleep uses 175 w/hour, keeping it awake for the convenience of their card is unacceptable.

    When the computer is first booted up the card works fine .. when the computer awakens from sleep the card is unable to access power again. Sonnet said they are working on the problem and will either come out with a new card or a driver update for this one.

    IF you have an external 3.0 that does have it's own power source (i.e., plugged in to a wall outlet) then the card is great and data transfer is awesome.

        I installed this in my aging '08 Mac Pro and it has helped a lot with handling this changing times we live in! It used to take 27 mins to download a 64gb CF card, now it only take 11 mins!

        No issues with the card so far.

        Using this successfully with a Mac Pro (5,1) and Windows 7 via Bootcamp to drive two Kinects for mocap. Be sure to download the latest drivers from http://sonnettech.com (Windows drivers link to another provider). Would have given this 5 stars if there were more than two ports and if it was cheaper.

        I needed a fast HD for video editing with my MacPro. Wanted to use USB 3.0 Hard drives and CF card readers. The Allegro works well with the self powered hard drives I have, but doesn't work with ANY of the bus powered Hard drives i have, nor does it work with ANY of the CF card readers I have. (they say it works with the Lexar pro - but it didn't) When using it with USB 3.0 HDs, there is RF interference with my wireless bluetooth mouse, and the mouse becomes erratic.

I am using a 4tb western digital external hd for time machine backups and it is crazy fast. As an inexpensive alternative to thunderbolt this is a no brainer

                      I tried to add a USB 3.0 card (from Japan) to my MacPro last year with no success. I saw this card and it had Mac Pro support.

                      I ordered the card, and when I recieved it I went to the Allegro site and downloaded their drivers as per their instrucitons, and then added the card. Presto, I was able to attach 2 USB 3.0 Western Digital MyBook drives. The speed is much faster than before.

                      So this worked out of the box, with about 5 minutes install time. Great product, easy to install and it just worked.

                          Installed this with the intent on using it with my LaCie Rugged 3.0/TB drive. I know LaCies sometimes can be finicky, so when it didn't mount, I called Sonnet. This is a direct quote from the Tech Support guy I spoke to, "That card is a piece of junk." He said it barely generates the 500mA needed to spin up bus powered drives. Sonnet Tech Guy: "I would send it back and get one from another manufacturer". It did mount a WD Passport, but not 100% of the time. Do not waste your time with this if you intend to use it with Bus powered drives.

                                  Seems to run smoothly with a card reader, that said, I have not tried it with any other device, drive or other P&P. But he the down load speed is wicked fast.

                                      Not compatible with my mac late 2008. Won't mount disk properly and was has a few kernel panics. Research showed I was not the only one. Sent it back for reimbursement.

                                        This card does not work with the 2012 Mac Pro! Crashed the system twice, and kills bluetooth. Spoke with sonnet (really nice guys) who told me it was out of their control at this time, and to return it. When it did work it was blazing fast. Download a 16gb cf card before I had time to carry my gear inside.

                                                I'd read reviews on this product both pro and con. I went ahead and ordered it as Sonnet products have yet to disappoint me. Installation instructions were followed exactly along with downloading the correct driver from Sonnet's site. Installation took mere minutes in my MacPro. Coupled with a recently purchased Lexar dual slot reader, it works flawlessly....and FAST!

                                                    This was a super inexpensive way to upgrade my MacPro to handle the now industry standard USB 3.0 drives. Don't wait for Mac to do it because they are going to push Thunderbolt whether consumers accept it or not ... and anyone who knows Mac knows that they are ALWAYS RIGHT .. just ask them. Sonnet is also pretty much the best at this sort of thing. My confidence was high in buying the Sonnet product and there has been no problem with it.

                                                    After reading about problems with fitting a USB3 card in a Mac I was a bit apprehensive but this card fitted easily into my early 2008 Mac Pro and after downloading the driver from Sonnet had no problems using the Voyager S3 USB 3 to clone my boot drive. My mac even recognized this as a boot drive without problem.
