Wenn ich das hier richtig verstanden habe ja.
Another slightly more important catch is that a modification to a single sector requires the entire 4k block to be read, modified, and then written back to the disk. Seasoned RAID and SSD users are used to this sort of thing, as RAID stripe and SSD block erase sizes are typically multiples of 4k or higher. Increased use of RAID was what led Microsoft to change the default partition start from sector 63 to sector 2048. This change started with Vista and is included in Win 7. Those still running XP with a default partition will see a performance hit with these new drives, as each 4k cluster modified will not be properly aligned to the 4k blocks of the Advanced Format drive. Because 63 is not evenly divisible by 8, each 8-sector cluster written will result in 2 4k blocks modified on the newer drive.
