ORMATTED CAPACITIES
Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time. Supported block
sizes are 512, 520, 524, and 528. 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 specify 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 shown below.
