The block size is selectable at format time and must be a multiple of 4 bytes. Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed. To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product planning in one of two modes: Seagate designs capacity points at certain block sizes that Seagate guarantees current and future products will meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from generation to generation. The current guaranteed operating points for this product are: Capacity (Blocks) ST9300653SS ST9300553SS ST9300453SS Sector Size Decimal Hex 512 585,937,500 22ECB25C 520 573,653,848 22314358 524 566,007,800 21BC97F8 528 557,874,778 21407E5A ST9146853SS ST9146753SS ST9146653SS Decimal Hex 286,749,488 11177330 280,790,185 10BC84A9 275,154,368 106685C0 272,662,935 10408197 Savvio 15K.3 SAS Product Manual, Rev.
