On modern drives you want a cluster size of 4096 bytes or a multiple of that, aligned to a multiple of 4096 bytes. With smaller or unaligned clusters you get worse performance. That's because all modern drives have 4096 byte sectors, normally exposed as virtual 512 byte sectors for compatibility reasons.
