Best RAID 0 Strip Size?

[Aegis]

What's the best size for optimal hard drive performance? I couldn't understand this article that well:

16k/16k for benchmarks and regular day to day use.

64k/64k and 128k/128k for video editing and anything involving large files.

So then the optimal would be 64k for benchmarks and for large files?

hmm, interested in this too, will rebuild my raid once i get a final answer

Right now I am using 16k chunk size/16k stripe size for my windows . I have tried 16k/4k, 32k/32k, and also 64k/64k for my windows but I have come back to 16k/16k since I have found this to have the best performance. When I work with large video files I have them on a seperate raid 128k/128k partition.

Hmm...I see what you are saying. Because I was gonna get 4 15k rpm 147 gig SCSI hard drives RAID 0 and stick the OS and app installs on that and also use it as a scratch disk for vdo editing. And then I was gonna have 2 x 500 gig 7200 rpm Seagates for storage and backups also in RAID 0 with a tape drive as a back up for the whole system. So since the vid files are going to be store on the 1 TB array but the manipulation probably done on the scratch disk array...maybe it would be better if I created another array based on a SCSI setup separate for scratchdisk purposes?
