I remember reading a long time ago that the larger the cluster size, the faster the read/write to the hard drive (but at a slight loss to space). I have two Maxtor 250GB hard drives at RAID 0 through my Promise TX2000 RAID controller. I just defragged using diskeeper, and noticed that my cluster size was 4KB. Would I be at an advantage to change my cluster size to 64KB? If so, what programs do you suggest? Thanks everyone!
 
i think its like 4k per disk or somehting like that, i am running 64k and my raid 5 array in my server is running 128k :) <3 HP netraid cards :cool:
 
4k is the default NTFS cluster size
the larger the cluster size improves performance at the expense of increased slack.
Its generally accepted that throughput improvements on a stripe, level off when the cluster size equals the size of the stripe size.
