[QUOTE="mm1352000, post: 741607, member: 82144"] I'm talking specifically HDDs with [B]4KB sectors[/B] (physically), as opposed to the vast majority of older drivers which have 512B sectors. Many *but not all* green drives have 4KB sectors. Manufacturers have various labels and notations for differentiating (eg. WD uses the term "advanced format")... The block sizes that you mention are "virutal" sector sizes. In the past, they were multiples of the actual physical sector size -> natural alignment. Now with 4KB drives you have to make sure that you align the virtual sectors with the physical sectors or else you drop performance through the floor... [/QUOTE]
