    Sonnet USB3-PRO-4PM-E reviews

    USB3-PRO-4PM-E Allegro Pro 4-Port USB 3.0 PCI Express Card is rated 4.7 out of 5 by 28.
    Rated 5 out of 5 by from Works with Mac Pro and El Capitan and Bluetooth mouse I bought one and found that it works fine with the Apple bluetooth mouse and El Capitan 10.11.5. on a Mac Pro 5.1 2012. Previously I had another usb card (no name brand) which did not allow me to use the bluetooth mouse with it, so I was concerned this would not work either but it does. I installed it in the 16 x pci-e slot, but Sonnet tech told me the 4x slot would be fine as well. They also said I could add a second card to the computer. They say this also supports ios device charging if you download the driver. I've only had and tested it for a day, but it seems perfect and tech support got right back to me when I wrote. Highly recommended to get this and not a cheaper card that may not be compatible with newest OS-X

    Rated 5 out of 5 by from Makes the silver towers relevant again This card not only connects high performance external storage to your aging Mac Pro, it makes ingestion of large video projects and numerous raw still captures to be quick and efficient. The throughput potential of thunderbolt is obviously greater, but the real bottleneck for data transfer is usually the performance of the target device. Unless you are transferring data between SSDs, USB 3 is as good as it gets. This card is easy to install, its performance is rock solid, and it's a bargain at twice the price. Buy it.

    Rated 5 out of 5 by from Fast USB Port, Easy to Setup I bought this for my 4.1 Mac Pro and it's just what I needed. It was extremely easy to install and the USB's all work great, unlike other boards I've used in the past. I would definitely recommend this product.

    Rated 3 out of 5 by from I'm not entirely happy so far. Hoping for software fixes Would I recommend? Sort of. Two Problems: 1. My drive keeps dismounting and I get an error about that 2. My blue tooth mouse went haywire. It won't even track, so I bought a blue tooth mouse for now. I have a Mid 2010 Mac Pro. I put in the PCI Card when I did my upgrade to Mac El Capitan. I use an external LaCie D2 drive for my Time Machine backup. For some reason the drive plugged into the USB 3.0 port keeps dismounting. I haven't figured out why. I keep hoping an update will come along for El Capitan or the USB Card. So far I haven't chased the problem to its end. So, in short, it's too soon to tell. I would recommend the card, but I have had problems that I think I can pretty directly relate to the card. I think it is creating interference with my blue tooth, and there appears to be an interaction issue with the hard drive. Generally the drive dismounts after a Time Machine backup. I'll have to turn off Time Machine and see if the drive stays mounted.

    Rated 5 out of 5 by from Boost a Mac Pro 2008 Works perfectly in a Mac Pro early 2008 (3,1). Speed boost on my USB 3.0 devices (card reader, external HD). No need to install drivers. Running El Capitan MacOS 10.11.5

    Rated 5 out of 5 by from Nice update for my old friend + magic mouse update! Not much to say except this card just works. My USB 3.0 drives now work as they should. I DID have the trouble with my Apple bluetooth mouse as others also have noted in previous reviews but I have always had some trouble with my Magic Mouse over the years but when I installed this card the Magic Mouse was all but unusable. SO I SET OUT TO FIND A SOLUTION AND I DID!!! If you hold the OPTION key down while pointing your mouse at the BT icon at the top of your Mac screen you will be able to see the signal strength from your Magic Mouse. Anything higher than -70 dbm will give you connection issues with your Magic Mouse. I was having that very problem and the problem was amplified by the addition of my Sonnet USB 3.0 card. Solution? Put an external antenna on the bluetooth card. I did it. I added an external 2.4Ghz antenna to my trusty Mac Pro 5.1 (2012) and now my signal strength from my Magic Mouse is a constant -58 dbm and my Magic Mouse works better than it ever has before on my Mac Pro. Now my USB ports and up to date and running good as is my Magic Mouse. Added bonus is I can see all kinds of BT devices in my immediate area because of the new antenna. All parts are readily available and no modifications to the Mac or its case are required.

    Rated 4 out of 5 by from Works as advertised, mostly My system is a mid-2012 MacPro 5,1 running 10.10.5. My previous USB 3 card was incompatible with Yosemite, and the maker has no plans to release an updated driver. I connect two powered USB 3 hubs and two USB 3 hard drive docks with this card. All the hubs' ports appear to work normally. I experience drive-mount failures about 10% of the time, rather than 50-60% of the time as was the case with my earlier USB 3 card. The Allegro Pro appears to be mostly Yosemite-compatible with driver v.1.01.
