my understanding (and I'm still trying to learn more) is that the speed advantage is not utilized until you get a larger file, so mp3's dont really give a bonus. I would think that large movie files (700MB) would have a noticable difference.
Like you, I'm trying to get the straight info so I can make a decision on my rig.
If anybody knows anyhting about performance stats on these RAID 0 systems please let us know!
I'm curious about the differences in files sizes and file types too.
Will it be better for OS, APPs, or Media (large video).
