Seagate Enterprise Capacity 3.5 HDD v5 SAS Product Manual, Rev. E 14
3.5 Formatted capacities
Standard OEM models are formatted to 512 bytes per block for 512 native drives. The block size is selectable at format time. Supported block sizes
are 512, 520, 524, and 528 for 512 native 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:
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.
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.
3.7 Factory-installed options
Users may order the following items which are incorporated at the manufacturing facility during production or packaged before shipping. Some of
the options available are (not an exhaustive list of possible options):
• Other capacities can be ordered depending on sparing scheme and sector size requested.
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit damage. Units
shipped individually require additional protection as provided by the single unit shipping pack. Users planning single unit distribution should
specify this option.
•The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM drive shipped, but extra cop-
ies may be ordered.
