5.0 Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all interface timings, power supply voltages, environmental requirements and drive mounting constraints. Seek error rate Read Error Rates1 Recovered Data Unrecovered Data Miscorrected Data Less than 10 errors in 108 seeks Less than 10 errors in 1012 bits transferred (OEM default settings) Less than 1 sector in 1015 bits transferred Less than 1 sector in 1021 bits transferred Interface error rate MTBF Service Life Preventive maintenance Less than 1 error in 1012 bits transferred with minimum receive eye. Less than 1 error in 1014 bits transferred with typical receive eye. See Section 9.6.3, "Differential PECL input." on page 68 1,400,000 hours 5 years None required 1. Error rate specified with automatic retries and data correction with ECC enabled and all flaws reallocated. 5.1 Error rates The error rates stated in this manual assume the following: • The drive is operated in accordance with this manual using DC power as defined in paragraph 6.2, "DC power requirements." • Errors caused by host system failures are excluded from error rate computations. • Assume random data. • Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry time. 5.1.1 Recoverable Errors Recoverable errors are those detected and corrected by the drive, and do not require user intervention. Recoverable Data errors will use correction, although ECC on-the-fly is not considered for purposes of recovered error specifications. Recovered Data error rate is determined using read bits transferred for recoverable errors occurring during a read, and using write bits transferred for recoverable errors occurring during a write. 5.1.2 Unrecoverable Errors Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 1015 bits transferred. Unrecoverable Data Errors resulting from the same cause are treated are 1 error for that block. Savvio FC Product Manual, Rev. D 17
