I recently put together a Synology clone NAS and I'm considering getting 10GbE to maximize transfer speeds. Ideally, I'd like to use SPF+ connections (for cost reasons). 1. Are there any off the shelf 10GbE cards that works with Mac Pros? 2. Which commercial "made for Mac" work well on Mac Pros? I'm always very worried about potential issues with drivers. Historically, I've always tried to avoid installing 3rd party drivers whenever possible. Thanks in advance.
