Best way to set up a huge 10~20TB for camera surveillance?
I will be building a computer soon. This computer's only purpose will be camera surveillance which will be running 24/7. We need a lot of storage, at least 10TB if not more, as this will have 4x 3MP cameras (2048x1536@15fps) and 12x 2MP cameras (1080p@30fps), which would mean 10TB should cover a month (300GB/day on average)
What type of drives should I use to have the best endurance? Reliability isn't crucial, but bang/$$ is. Recommendations for very long lasting PSUs that work great 24/7 would be good too (should I be going into server PSUs?). Would Ivy Bridge do or is X79 better?
This will be running Windows 7, probably ultimate 64 bit of course, is there anything I should be worried about when building a comp with such a huge amount of disk space?
Can I just use the hard drives separately instead of RAIDing?
