DC Magnetic Field Immunity
1, 2, 3
400 Gauss, RMS
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 mag-
net 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.

Rated workload
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 work-
load rate limit is in units of TB per calendar year.
