Finally found a USB3 card from my original Macpro 1,1. The USB3 works perfectly. Haven't tried the eSata yet but no problems with my Lexar USB3 card reader or Seagate hard drives. I had the Lexar USB3 card but it only works with their own drives….nothing else.

Even after contacting their support and troubleshooting the issue, my Mac Pro 2008 does not read the card as USB 3. During testing, the transfer speed is a little faster than USB 2. The eSATA ports are a good addition. Over all a bit of a let down.

Works with Mac Pro Aug. 7 2012

This is the only USB card that I've been able to get to work in my 2009 Mac Pro, and so far it's great. It's working in Mountain Lion with a Lexar USB 3 Card Reader and a Firmtek eSATA drive enclosure.

BOOT PANIC ON MAC PRO -- USB 3.0 Does it Work? May 21 2013
By gb - Published on
Third update: OWC sent me replacements of both Caldigit card and their Voyager Q external device to see if the items had manufacturing defects.

Long story short, the replacements had the same panic kernel as described. The Mac Pro boots fine if the Voyager Q is off or doesn't have a drive inserted, however, I get a panic kernel every time if the Voyager Q is on, a drive is inserted, it is connected via USB3, and I boot the Mac. The work around is easy enough, just leave the Voyager Q off when booting.

Second update: I am updating my original two-star review to four stars now that I've had a few weeks to work with it.

I suspect the panic kernal is a conflict with the OWC macsales new Voyager Q bridge, OWC has offered to send me new replacements for the Caldigit and Voyager Q I just purchased from them. I suspect that won't solve the problem, but I will update this if I can solve it...

Otherwise, the Caldigit card seems pretty solid as advertised, including no sleep issues on my 2008 Mac Pro 3,1.


I just bought a CalDigit FASTA-6GU3 new from macsales and within several boots after installing the USB 3 driver, I hit a Panic kernel. CalDigit's USB driver "com.CalDigit.driver.CalDigitUSBxHCI(1.3.8a2)[F4AA3EBC-9193-31D6-89AF-D7D1AF1" was in the top of the Apple crash report as a prime suspect.

My two stars will be updated as I get more information, but feel users should be aware of this before possibly wasting their time (like I am) troubleshooting and returning stuff that don't work.

First I am an experienced Mac troubleshooter and workflow consultant (this is my first experience with Caldigit).

The workstation is a 2008 Mac Pro 3,1, 20GB RAM, system 10.7.5, only two PCI cards installed, a 5770 GPU (driving 30" Apple monitor and 24" NEC) and the Caldigit card (both running in the two 16X PCI 2 slots). I installed the latest USB3 driver fresh off Caldigit website. No other 3rd-party USB hardware/software previously installed, I run very lean systems with no system haxies.

The problem occurred when I had a new OWC Voyager Q connected via the Caldigit Firewire 3.0 -- the Voyager was on with a hard drive inserted -- on booting the Mac Pro, I hit the panic kernel (this Mac Pro never had boot problems before). After I turned the Voyager off, the Mac Pro booted without problems. The problem could be in OWC's bridge or with the CalDigit driver, but there appears to be a conflict either way.

My main concern is Caldigit's support (macsales offered to replace their card). Caldigit sent me a lengthy outline of troubleshooting routines that included everything from reinstalling their driver to erasing my hard drive and installing the OS fresh.

While it would only cost me a couple more hours to put in a new hard drive, erase it, install the OS, run the updates, add on the Caldigit driver, and reseat the PCI cards -- i feel the problem is with their driver conflict with the Voyager Q external.

By Caldigit's email and no response to my follow up, Caldigit seems to expect me to do all their troubleshooting -- I've been in this business a long time to waste more time proving a conflict since the crash report lists the Caldigit driver near the top of the report, and it looks like a bug to me.

I hope I can update this with more positive news even if it is returning the items without losing any more time...

Does Work with the Mac Pro 5,1 (2010) Hexacore March 1 2013
By Marc R. Feldesman - Published on
Verified Purchase
I bought this card to replace a flaky Sonnet Allegro USB 3.0 card. The Caldigit offered the two extra sata ports, which I'm unlikely to use right now. My initial experience with the board was totally negative. Upon initial installation (card and drivers), I received a fatal exception and it brought the whole system down. After finally getting the system to reboot successfully (Mountain Lion, 10.8.x), I was able to get to the CalDigit site and find slightly updated drivers for Mountain Lion. My Mac Pro is the latest model, a 6 core 3.33 GHz Xeon with 32 GB RAM. However, my Hoodman USB 3.0 Steel CF/SD card reader appeared dead and non-functioning. I know from prior experience that the choice of card readers is a particular problem with Mac Pros and USB 3 cards. I keep several around for that reason. I decided to try the more standard Lexar USB 3.0 card reader. Upon unplugging the Hoodman cable from the USB 3.0 port, the system kernel panicked and shut down (no grey screen, just jet black). I turned the machine off. Let it sit for awhile, and then rebooted. Upon successful reboot, I plugged in the Lexar USB 3.0 card reader, made sure I had ITS latest firmware (I did), and proceeded to insert a CF card. Blue lights came on the card reader, and my photo cataloging program came to life. Success! Buoyed, I tried to import all the photos and they just screamed through (as screaming as 40MB files can go from a Nikon D800). Import successful. Next try, an SD card. Same result.

My conclusion is that like all of the other USB 3.0 cards I've tried (Sonnet, LaCie, and now CalDigit), the CalDigit will work with the Lexar reader consistently. None work with the Hoodman, which is unfortunate because the Hoodman is the only one with pin protectors for the CF card. Lexar provides consistent high speed, but without the protection afforded by the Hoodman.

Now, for the significant admission. I'm a Mac developer and I've been running the beta versions of the latest iteration of Mountain Lion. The fact that CalDigit runs out of the box and with updated drivers with the latest beta (12, I think) of Mountain Lion means that it is the most up-t0-date hardware around. Although it costs twice as much as the other USB 3.0 adapters, the fact that it works is a salient point.

I've found none of the other USB 3.0 cards I've tested work reliably with Mountain Lion; even if they support it, support is generally broken with every upgrade. So, I'm hopeful that CalDigit's card, which is extremely well-built, will be the solution to my needs.

Will not work with scanner March 8 2013
By Tom California - Published on
Verified Purchase
I purchased this card for mac pro late 2008 to take advantage of usb3 for a new ix500 scansnap scanner usb3 option. Installation was easy. I downloaded the usb3 drivers without difficulty. I plugged in my scanner and my computer went black and shutdown. I called cal digit support and got a prompt response. They informed me that the card is only designed to support storage devices and not scanners. I did not see this in the documentation before ordering. Other than the inability to support scanners my experience was good. I am, however, giving this 3 stars to warn others of the problem.

Works great on Mac Pro 3,1 2008 Sept. 6 2013
By M. Mich - Published on
Verified Purchase
I did a lot of research into adding USB 3.0 to my late 2008 Mac Pro 3,1. This card seemed to have the best reviews - really the only card that seemed stable across all Mac Pro models. Luckily, the card does work great!

I pulled out my older 3G eSata 2x PCI card and popped the Caldigit into the same PCI slot. Booted up the Mac, and the eSata worked out of the box. eSata ports recognized and transferred files between both of my external devices - a single 2TB drive, and a 4 x 2TB Probox enclosure.

The card comes with an installer CD which includes USB 3.0 drivers for OSX 10.6, 10.7, 10.8 as well as Windows. I installed the 10.6 (I am running 10.6.8 Snow Leopard on my Mac) driver, and rebooted. Upon restart, I connected my external USB 3.0 drive and it worked great! Fast transfer speeds, and seemed stable.

I finally have USB 3.0 on my Mac!
