3.5 Formatted 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, 528, 4096, 4160, 4192, and 4224. 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. The Capacity stated is identical when the drive is formatted with or without PI enabled.
3.6 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.
