I believe that what you are referring to as a Thunderbolt NAS ("Network Attached Storage") is more properly referred to simply as an external hard drive or array of hard drives having a Thunderbolt interface. Thunderbolt is not usable for general purpose networking, but rather for direct connection to a specific computer that is located within a short distance.
There are some available from LaCie and Promise, although they can be quite expensive. Here is a listing of them at the Apple Store. The models shown are also widely available elsewhere.
Interface adapters are also available to adapt between a Thunderbolt interface and Firewire, USB, and possibly eSATA, although I have no particular familiarity with them, or with how well they work.
I don't know of any DAC's that have Thunderbolt interfaces. I believe that Apogee Electronics announced some time ago that they would be introducing one for professional applications, but I'm not sure that it exists yet.
