The current guaranteed operating points for this product are: Sector Size 512 520 524 528 ST3600057SS ST3600957SS ST3600857SS Decimal 1,172,123,568 1,147,307,694 1,132,015,600 1,115,749,560 Hex 45DD2FB0 446286AE 43792FF0 4280FCB8 ST3450857SS ST3450757SS ST3450657SS Decimal 879,097,968 860,480,771 849,011,700 836,812,167 Hex 3465F870 3349E503 329AE3F4 31E0BD87 ST3300657FC ST3300557FC ST3300457SS Decimal 585,937,500 573,653,848 566,007,800 557,874,778 Hex 22ECB25C 22314358 21BC97F8 21407E5A 4.6 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. 4.7 Factory-installed options You 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, may be included with each standard OEM drive shipped. 8 Cheetah 15K.7 SAS Product Manual, Rev.
