while operating and a mere 4.75
Watts during spin up.
1 million hours MTBF
Best-in-class reliability for small
form-factor AV storage.**
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.
* A sone is a subjective unit of loudness as perceived by a person
with normal hearing.
** Based upon dual tuner system operating in typical 30°C air ambient
environment.
