Hard drive cluster size in WinXP & Raid

I am building a dual cpu AMD based graphics machine. I am using 4 IDE hard drives (2xraid 0). Two 20 gb hard drives (raid 0) for O.S. & software plus two 60gb hard drives (raid 0) for data. I was told that with larger file sizes such as graphics images, if I were to increase the hard drive cluster size on the data drives in the raid array form the standard 64kb to 256 or 512kb this would noticeably speed up the system. This settings modification is available on my ATA133 ide raid card.
I noticed that while installing XP, when you choose the file system you want to use (NTFS or FAT32) it also gives you the option of choosing cluster size, all the way up to 2048kb. I know that increasing the cluster size decreases storage efficiency, but I'm really not concerned about that at this point.

How do the raid card settings & WinXP settings interact ? Do these two settings have anything to do with each other ? Does it really speed things up with graphics ?

***TOTALLY CONFUSED***

Any input would be appreciated

No. Your RAID array is seen as one big drive by the OS. You can partition it, format it, change the cluster size, whatever, *exactly* like you would a single drive. Many people still don't get this, and postulate all sorts of bizarre connections between the two.
