DC Magnetic Field Immunity
1
Field in Gauss at the drive envelope. Testing per procedures 20800109-349 and 20800109-350.
2
Passing Field in Gauss at the drive envelope. In practice, testing is conducted using a fixed distance from the bottom of the
magnet to the top of the drive. Calibration of the field vs. distance is done with a Hall probe with no magnetic materials present.
3
Testing to be done with magnet .375" dia. x 0.100" Ni-plated NdFeB; B,~11.5 kG, magnetized along its length; the magnet is
oriented with the length perpendicular to the drive cover/PCBA. Drive to be properly secured during test.

Average annualized workload rating: <55 TB/year.
The AFR specification for the product assumes the I/O workload does not exceed the average
annualized workload rate limit of 55 TB/year. Workloads exceeding the annualized rate may
degrade the product AFR and impact reliability as experienced by the particular application. The
average annualized workload rate limit is in units of TB per calendar year.
