|Nonrecoverable read errors||1 sector per 10^15 bits readAnnualised Failure Rate (AFR)*|
|0.73% based on 8760 POH|
|Maximum rate of <300TB/year
Workloads exceeding the annualized rate may degrade the drive MTBF and impact product reliability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours.
Workload Rate = TB transferred * (8760 / recorded power on hours).
|Supports Hotplug operation per Serial ATA Revision 3.3 specification||Yes|
|Notes||* One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
