I've become curious after leaving this at default so many times... What does the NTFS "Allocation Unit Size" setting do, when you're formatting an NTFS volume?

I'm formatting a partition on a 4-drive RAID-0 with 64KB block size. Is there any advantage to setting the NTFS "allocation unit size" setting to anything in particular, as opposed to leaving it at default? Should I set it to 64KB maybe? Does this setting make a difference in raid?

Not really. I read a review where some geezer did a test on it. Didn't seem to matter what he used. Default should be fine. I always figured you might as well set the cluster size to equal stripe size but in reality it makes bugger all difference.
