Operating
HDD class
Class 1: Highest performance, reliability, and data integrity
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.
