I'm looking for a recommendation from anyone with hands-on experience with USB 3.0 PCIe cards. I need it for an external Blu-Ray drive that I'll be using to back up a data base onto rewritable Blu-Ray discs (BD-E). I'm currently running OS X 10.6.8 on a Mac Pro Quad-Core 2.8GHz (mid-2010), but I have ML 10.8.5 installed on another drive, and I'm gradually making the transition as I test all my apps and plugins for ML compatibility. So, I'll need to have something that works with 10.8.5. Last I knew, Highpoint's card had problems with Mountain Lion, but they might have fixed it by now. I expect that Sonnet's card would work OK, but I'd appreciate anyone's actual experience. Thanks!
