It can support up to 5 simultaneous HD video streams and is perfect for DVRs, set top boxes and digital video surveillance systems. The Advanced Format (AF) technology adopted by WD is a more efficient media format that enables increased areal densities.
The 2.5" internal hard drive is low on power consumption, drawing less than 2 Watts while operating and 4.75 Watts during spin up.
It uses SilkStream technology which is optimized for smooth, digital video playback of up to five simultaneous HD streams.
SilkStream is compatible with the ATA streaming set enabling you to use standard streaming management and error recovery options.
The hard drive has been engineered to provide maximum reliability for demanding always-on environments.
PWL (Preemptive Wear Leveling) is a technique in which the drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications.
The ultra cool, quiet drive is the perfect solution for a variety of multimedia applications and fan-less environments where the drive operates below 149°F (65°C) base casting temperature.
The noise levels have been minimized to less than 1 sone*, virtually below the threshold of human hearing.
*A sone is a subjective unit of loudness as perceived by a person with normal hearing
It is ideal for video surveillance, DVRs/PVRs, set up boxes, high-end audio systems, karaoke players and digital signage.
