RELIABILITY

 

 

Component Life:

5 years

 

Preventive Maintenance (PM): Not required

 

Contact Start/Stop:

50,000 cycles at ambient,

 

 

35,000 at Environments

 

Annualized Failure Rate (AFR)

No greater than 0.58 percent

Drive reliability is closely related to the temperatures the drive is exposed to. The AFR is based on an operational design temperature ambient of 86° F (30° C)

Recovered read errors1

Uncorrectable read errors2

 

1 event per 1015 bits read

1.Recovered read errors are errors which require retries for data correction. Errors corrected by ECC on-the-fly are not considered recovered read errors. Read on arrival is disabled to meet this specification.

2.Uncorrectable read errors are those that are not correctable using an Error Correcting Code (ECC), or retries within the retry limits specified in the mode pages. The drive terminates the command either when a repeating error pattern occurs, or after both the specified number of retries and application of triple burst error correction fail to correct the error.

3.A seek error occurs when the actuator fails to reach or remain on the requested cylinder, and/or the drive requires the execution of the full calibration routine to locate the requested cylinder.
