ORMATTED CAPACITIES
Standard OEM models are formatted to 512 bytes per block. 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 UNIT 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 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. The Capacity stated is identical
when the drive is formatted with or without PI enabled.
