I was looking at the specs of these three boards and want to understand the D1 record rate info better. I realize you don't need anything near 30 frames per second to get decent footage, but I still want to understand this. http://www.avermedia-usa.com/surveillance/userfiles/image/files/NVCardComparison.pdf shows the following D1 record rates
6240e8 240
6240e16 80
6480e16 160
So if I read that correctly, only the 6240e8 records at 30 frames per second into all 8 channels. The best the 6240e16 can muster is 10 frames into 8 channels. Even the 6480e16 seems to only do 10 frames into all 16 channels, or 20 into 8. So if I am correct, the 6240e8 seems to be the best value performance wise.
Am I making any sense?
