3.4 Reliability • 1,600,000 hour MTBF (Annualized Failure Rate (AFR) of 0.55%) • Incorporates industry-standard Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) • 5-year warranty 3.5 Formatted capacities Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time and must be one of the supported sizes listed in the table below. 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: Capacity (Blocks) ST3450856SS ST3450056SS (FDE) Sector Size Decimal Hex 512 879,097,968 3465F870 520 860,480,771 3349E503 528 836,812,167 31E0BD87 ST3300656SS ST3300056SS (FDE) Decimal Hex 585,937,500 22ECB25C 573,653,848 22314358 557,874,778 21407E5A ST3146356SS ST3146756SS (FDE) Decimal Hex 286,749,488 11177330 280,790,185 10BC84A9 272,662,935 10408197 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 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.
