
Class 2: A second tier of performance, reliability, and data integrity
HDD I/O throughput degradation SPEC
Pass/Fail Criteria

No functional failure during test or post-test diagnostics.

Requirement to pass test is based on IOMeter data throughput (in IO’s per
second) expressed as a percent of Test HDD maximum theoretical baseline
performance

Class1: > 90% of baseline for 4K random writes and > 80% of baseline for
128K sequential writes.

Class2: > 85% of baseline for 4K random writes and > 75% of baseline for
128K sequential writes.

Mix: > 80% of baseline for 4K random writes and > 70% of baseline for
128K sequential writes.
