SilkStream
™
– Optimized for smooth, continuous digital video playback of up to
twelve simultaneous HD streams. SilkStream is compatible with the ATA streaming
command set so CE customers can use standard streaming management and error
recovery options.
IntelliSeek – Calculates optimum seek speeds to lower power consumption, noise,
and vibration.
IntelliPower – A fine-tuned balance of spin speed, transfer rate, and caching algorithms
designed to deliver both significant power savings and solid performance.
IntelliPark – Delivers lower power consumption by automatically unloading the heads
during idle to reduce aerodynamic drag.
Preemptive Wear Leveling (PWL) – The drive arm frequently sweeps across the disk to
reduce uneven wear on the drive surface common to audio video streaming applications.
