I have 2 120GB SATA Seagate Barracuda 7200.7's in a Raid 0 config. I use my PC primarily for video editing and gaming. Are there any tests conducted on a webpage that compare dv and gaming performance between different Raid 0 stripe sizes? What stripe size yields the best performance for my current setup?
 
Given RAID-0's poor scaling in game loading, stripe size isn't going to be a huge dfiference, regardless of what you set it at.

Your video editing however will benefit from a small block size that boosts sequential throughput.
 
So 16k is the best for video editing? I always thought that 64k or 128k was the best since video editing involves transfering large files. Let me know your opinion on this subject.
 
I think that the faster your disks are, the lower stripe you can use effectivly. Thats just from my expirance. When I had 2 - 7200rpm 2MB cache old ATA 66 Drives in raid 0. I used 128K and it was good.

For my Dual Raptors, 16K seems like the sweet spot.
