What do you guys think about this RAID system they are always pushing? I've heard that a 1TB Esata drive should handle HDV just fine but if that's not the case I should start looking into RAIDS.
RAID setups are unnecessary (and potentially risky) unless you frequently use many video and audio layers simultaneously in a decompressed format. Consider that a single layer of HDV 1080i is only 25 Megabits/second and that's the same as 3.125 Megabytes/second (1 byte = 8 bits), while a single modern hard drive can sustain at least 25-50 Megabytes/sec or several layers of HDV.
I regularly do 2-3 layer HDV edits on my laptop using the Canopus HQ codec, which requires even more drive throughput than HDV, and while this bogs down sometimes it's functional.
