Optimal cluster size for 64K striped NTFS volume?

Archived from groups: microsoft.public.win2000.file_system (More info?)

I am looking to optimize the Read performance of a given
volume.

Given:
Windows 2000 Server SP4
Software Raid-0
Two ATA/100 HD's each on a separate controller.
Volumes will be formatted NTFS.

If Raid writes 64KB stripes, how does that influence my
selection of a cluster size when I format these drives?

I am thinking that it might be wise to select something
greater than the 4K default, but have been unable to find
any performance study concerning cluster sizes in RAID
enviroments.

Thank you in advance for any assistance.

    The most important question is: What is a normal disk access for the array?
