Standard OEM models are formatted to 512 bytes per block. The sector size is selectable at format time. 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:

1.

Seagate designs specify capacity points at certain sector 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: 

2.

Seagate drives also may be used at the maximum available capacity at a given sector size, but the excess 
capacity above the guaranteed level will vary between 10K and 15K families and from generation to gener-
ation, depending on how each sector size actually formats out for zone frequencies and splits over servo 
bursts. This added capacity potential may range from 0.1 to 1.3 percent above the guaranteed capacities 
listed above. Using the drives in this manner gives the absolute maximum capacity potential, but the user 
must determine if the extra capacity potential is useful, or whether their assurance of backward and for-
ward compatibility takes precedence.
