... actuator uses piezoelectric motion to fine tune the head positioning to the recording head and media as well as of additional testing under actual workloads in testing with thermal cycling to maximize performance. RAID-specific, time-limited error recovery (TLER) Prevents drive fallout caused by the extended hard drive error-recovery processes common to protect the data. NoTouch™ ramp load technology The recording head never touches the disk...
