Recommended Block Size For RAID 0

I am setting up a RAID configuration (Striping, no Parity, Mac G5, OS-X) and was curious what the recommended Block Size should be. Content is primarily (but not limited to) Images created with Adobe Photoshop CS2 and range in size from 1.5MB to >20MB. The default for OS-X is 32K chunks of data.

Drives are External FW-400.

Many thanks, and Happy Holidays to all!

PowerMAC G5, OS-X 10.4.6, 1.7TB Storage, Mac OS X (10.4.6), 6.5GB RAM, 1.7TB Storage

If it is just scratch, run some benchmarks with it set to 128k and 256k and see how it feels with each. The default is too small, though some find it acceptable for small images. For larger files you want larger - and for PS scratch you definitely want 128 or 256k.
