Not only for this Fujitsu, but for all SCSI hard drives, 1024 byte blocks are better than (or in a few cases as good as) 512 byte blocks. The reason is that the filesystem writes files in increments of 1K. Thus if the disk is formatted to 512, blocks get used in pairs. There is an overhead cost to be paid for this. Formatting the drive to 1024 byte blocks may yield a capacity increase of up to 5%, and a performance increase smaller than that.
