5.0 Reliability specifications
The following reliability specifications assume correct host and drive operational interface, including all inter-
face timings, power supply voltages, environmental requirements and drive mounting constraints.
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 Section 6.2
• 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
Recovereable 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 recov-
ered 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 10
16
bits trans-
ferred. Unrecoverable Data Errors resulting from the same cause are treated as 1 error for that block.
Seek error rate:
Less than 10 errors in 10
8
seeks
Read Error Rates

bits transferred with typical receive eye.
See Section 9.6.4, "FC Differential input." on page 72
Mean Time Between Failures (MTBF) 1,600,000 hours
Annualized Failure Rate (AFR): 0.55%
Preventive maintenance: None required
