Can be good or bad...
In general, disc brakes are more expensive than their rim brake counterparts. They weigh more, are more complex and can at times make some serious noise when doing their job.
On the positive side, the best designs stop better than anything else - particularly in wet weather or muddy conditions. They don't have a brake arch to jam with mud or snow, their weight is carried at an optimum location in relation to the wheel, and the good ones are easy to modulate, taking "one-finger" power...
Hydraulic discs are generally superior to mechanicals (although I think Avid's mechanical discs are excellent) and can feel "automotive" in performance.
I'll make a very general (I know, this is stupid of me) assertion that if you don't ride in wet or muddy conditions, you probably don't absolutely need disc brakes. Downhill mountain biking and loaded touring would be a couple of exceptions to that rule.
Personally, I love discs for their feel and performance. I have a set on my cyclocross bike and on most of the family MTB's. I don't know about the particular brake you are asking about, but if you Google for a review of them, I'm sure you'll get some answers. Some BF members will probably have an opinion on them as well.
Just thought I'd give you a little basic eduacation to start with.
