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
