## Questions & Answers

**Q: Does the USB 3.0/Firewire 800 card Combo PCI Express card support hardware RAID?**
A: You should call Sonnet tech support and address this question to them directly. Go to their website and locate the toll-free number and ask for tech support. I've spoken to them a half dozen times in the past, they are located in the US, their tech support people are knowledgeable and I've almost always gotten someone on the phone immediately who could answer my question, and once or twice I was directed to someone else at Sonnet who was better-versed to answer my specific question and it took only 10-15 minutes for them to return my call.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Well built, works in Macs with no additional kexts
  

*by J***K on Reviewed in the United States on March 12, 2014*

The usual Sonnet-quality product. Provides 3 Firewire 800 and 4 USB 3.0 (2 from board bracket, 2 from accessory USB 3.0 bracket or computer case front panel USB 3.0 connectors). The photo is incorrect in that it shows a board with no external power connector but the actual board does have the required 4 pin Molex power connector. The board has a Fresco Logic FL1100-1Q0 integrated circuit for the USB3 interface and an LSI L-FW643E2-F39G integrated circuit for the Firewire interface. Interface to the PCIe bus is handled by a Pericon Semi PI7C9X2G 304SLAFDE PCIe Gen 2 integrated circuit to interface with the motherboard's PCIe bus for a pure PCIe connection, unlike TI chipset-based boards which use a PCI-to-PCIe bridge chip to interface to the motherboard's PCIe bus.This board works in hackintoshes with no additional kexts (tested in OS X 10.8.x), except Gigabyte Z77X-UD5H motherboards, which appear to have a BIOS issue that prevents all boards with the LSI/Agere Firewire integrated circuit from working properly.Expensive, but works very well and provides both Firewire 800 and USB3.0 interfaces in one PCIe board.

    Overpriced and took down my 4TB! Beware of restocking fees and slow refunds!
  

*by C***. on Reviewed in the United States on October 22, 2014*

On a 2013 Mac Pro Tower, Mountain Lion Mac OSX.  Get this instead, 1/2 the price, no return issues and worked without a hiccup: The Inateck 4 Ports PCI-E to USB 3.0 Expansion Card for Mac Pro.  I got this after and was a great solution.  When I received it, I installed the card and restarted with drives connected.  My striped 4TB RAID drive came up with the message "Initialize this device, unreadable by this Mac" instead of mounting and I was using it minutes before, working flawlessly.  Unfixable, destroy the remaining data by reformatting or start restoring files.  I had to get special RAID restore software and started that 2 week process.The USB 3.0 read/write was under standard for speed with the correct cables, when benchmarked it came up at about 75%, of average for 3.0 and yes, I know about Mac and USB 3.0 dropping to slower speeds. The Firewire didn't work at all until after weeks of trying drivers, etc. When I finally got the Firewire to see the drives, data transfer averaged at about 50% of FW 800. On boot the screen would flash brightly before starting up with this card in the PCIe slot.Anyway, $100 for the card, $100 for the RAID drive rescue and restore software, a 15-25% restocking fee... I'm guessing $25, about 25 hours of work (priceless time)  restoring my system and about $5.00 postage to return it. This thing cost me $230 to try it since I haven't gotten my money back yet either.  That's the absolute worst thing: I have had this card returned for a week or two and I still can't seem to get them to process the return!  Where's my money? Way below my average Amazon experience.  Not worthy of the association with them.
