I'd be using it to capture uncompressed 1080p video. Would this board be up to that? I don't see the processor having problems, since it's not encoding, but some input from those knowing more than I would be appreciated.
The setup Shoikan was describing is using a port multiplier, so several drives are sharing a single sata link to the motherboard, which will increase capacity at the cost of speed.
If you are talking about truly uncompressed hd video in real time at 200+ MB/s, you probably want to use a raid-0 with a couple drives hooked to separate sata ports (and you'd fill up a pair of 1-terabyte drives with a few hours worth of video)
Copying with dd from /dev/zero to a test file I get 205MB/s onto a SSD with no raid, so theoretically you may be able to do what you speak of using raid-0 even with this board, however especially depending on the source/input connection you would probably be better with something with more processing power. Especially assuming you'd at some point want to compress that video.
However I am using a silicon dust tuner and can capture capture two 1080i HDTV streams simultaneously using the C60 with no problem. The streams are actually broadcast with MPEG2 compression, and run about 2-4GB/hr. Have no problem with the capture, could probably run 2 more if I had another tuner, but i do boot up the big computer once a week or so to compress those captures to x264 to reduce the size.
