Formatted capacities
Standard OEM models are formatted to 512 bytes per block for 512E (emulation) and 512N (native) drives and 4096 bytes per block for
4096N (native) drives. The block size is selectable at format time. Supported block sizes are 512, 520, 524, and 528 for 512E and 512N
drives and 4096, 4160, 4192, and 4224 for 4096N drives. 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:
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:

Programmable drive capacity
Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6) parameter
list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field indicates that the drive will not
change the capacity it is currently formatted to have. A number other than zero and less than the maximum number of LBAs in the Number
of Blocks field changes the total drive capacity to the value in the Number of Blocks field. A value greater than the maximum number of
LBAs is rounded down to the maximum capacity.
