Easy to add USB3
Installed this very easily into my 2009 Mac Pro six core Tower. I have a lot of data to archive and USB2 just isn't fast enough and the USB3 SSDs I have been using din't seem to like USB2 on the Mac at all and occasionally wouldn't boot, but that problem has gone . The addition of of the Sonnet card it has made backing up from mechanical hard drives to solid state drives much faster . Seems to work a lot faster backing up from a USB3 drive dock to a USB 3 storage device than from the internal drives . It was painless to install and worked straight away on startup

Wish I had gotten an Allegro to begin with. Just put it in and it works perfectly.

5 stars for Allegro USB 3.0 4 Port PCIe card = works with 2012 Mac Pro Tower!
I purchased this for the purpose of getting better speeds with my 2012 Mac Tower Pro. The card was delivered on 3 Aug 2018 = fast shipping. The instructions were simple; called to insert the board into a PCIE slot which I did. Started up my Mac Tower and didn't even need to download drivers. Hooked my Sony HDR-CX580 to download some pic and video. A lot faster than the 2.0 USB on the tower. Great product, easy to install, easy to use and so far I give it 5 stars. See pictures for details.BTW I am running macOS High Sierra ver. 10.13.6, 2 x 3.46 MHz 6 core Intel Zeon, 64GB 1333 MHz DDR3 memory, with ATI Radeon HD 5770 1024 MB graphics card.Thanks Sonnet for a great plug and play USB card.

Works except when rebooting
I may have been too harsh in my original review but the quirk this card has makes it frustrating to use. I does work great on both Linux and Windows. However, any time I reboot, either to the same OS or a different one, the card stops working. I have to fully shut down and start again for it work. I have updated my BIOS since getting this card so I'm not sure what could be causing this behavior.Original reviewSlotted the card and plugged in a spare keyboard. Worked great on Linux. Windows didn't detect and install a driver so I had to go to the website. Install failed the first time but worked on the second. Booted back to Linux and the card stopped working. Booted back to Windows and it still didn't work.

Fast, reliable
I installed my Sonnet Allegro USB 3.0 card in a 2009 Mac Pro, running El Capitan. No third party drivers were needed.The card is working flawlessly, unlike two other brands cards I'd tried on earlier releases of OS X.Of course, I tested it for speed ...(best viewed with fixed width font)Write Read Drive Interface Drive model, capacity----- ---- ------- --------- -----------------------1650 1922 ramdisk250 265 (root) SATA 3Gb Crucial_CT960M500SSD1, 1 TB Note: SSD150 144 backups SATA 3Gb Hitachi HDS724040ALE640, 4 TB120 118 tm SATA 3Gb Western Digital WDC WD30EZRX-00SPEB0, 3 TB31 33 wd5 USB 2.0 Western Digital WD My Book 1230, 5 TB150 150 wd5 USB 3.0 Western Digital WD My Book 1230, 5 TBThe interesting two lines are the last two … it’s the same disk drive,tested first via USB 2.0, and then via USB 3.0.In short, I can now write to my external USB 3.0 drive at SATA-like speeds!

This allows me to pull these drives out and still get similar if not slightly better speeds from these drives placing less stress on the ...
While many comments here focus on the fact that this card is plug and play (and it is) my focus on this install was to bring on a 4 SATA hard drive enclosure via USB 3.0. MacPro have 4 hard drive bays and I use them all. The problem is that they are using the power supply of the computer, create heat and block a bit of the heat from exiting the computer. This allows me to pull these drives out and still get similar if not slightly better speeds from these drives placing less stress on the MacPro. Are there drive issues? Only after sleep but no loss of data and I was not required to initialize or erase the drives to install them. Now I can bring them up as needed or just leave them quietly off. The main drive is a SSD in the PCIe 16x slot so she's plenty fast. I have 5 SATAs now that are backup drives and 4 that are entertainment - movies mostly which stream better through the USB 3.0 with better picture quality too!

Perfect for a classic Mac Pro
Ordered this card after a prior FebSmart USB card was acting really wonky. Works like a champ in my 2010 Mac Pro (5,1). 10/10
