I can see why it's taken so long from the January announcement to the late July availability of this card. The operation seems to be a complete shambles! 1. My card arrived with faulty firmware. 2. The cards do not ship with any drivers or documentation. 3. The downloadable pdf manual simply covers installation of the card and there are no instructions anywhere for operation of the RAID software, leaving you to guess how to set it up. The installation manual even has errors about the cabling. 4. The downloadable drivers/firmware/manual currently on the Caldigit website site are corrupted and will not unzip (both the Mac and PC drivers). 5. There is no way of installing OSX directly from the DVD onto a RAID. You have to first install to an external drive, then create the array, then restore your system onto the RAID. The many PC RAID cards I have had over the years simply came with a small driver which you install during the o/s installation. 6. The card will not boot at all with a 4 drive RAID 5 array, which was my reason for buying the card in the first place. After the chime, you just get a blank grey screen. Holding down Option doesn't work - you can't get past the grey screen. You have to boot from DVD and reset the startup disk to the external firewire drive. 7. Tech support were clueless beyond 'Err... have you tried the latest beta drivers..?' I've spent the entire week with my primary workstation out of action, initializing and reinitializing arrays and restoring my system over and over again, a 7 hour process every time, with no success. Very unimpressed - wish I hadn't bothered.
