In order to cater for the growing AV/DVR and surveillance market, Western Digital has just released a new 2.5-inch SATA hard drives series that they called the AV-25, which are designed to deliver high rate of reliability. How reliable, you asked? A Mean Time Between Failure (MTBF) rate of 1 million hours, to be exact.

-  Advance Format technology: Leading edge technology that delivers improved video quality and AV performance through enhanced error correction capability.

- SilkStream technology: Optimized for smooth, continuous digital video playback of up to five simultaneous HD streams. SilkStream is compatible with the ATA streaming command set so AV customers can use standard streaming management and error recovery options.

- Ultra-cool operation: A cool drive is a more reliable drive. WD continues to develop new and innovative ways to keep drives cool while they are operating.

- Quiet: Noise levels have been minimized to less than one sone - virtually below the threshold of human hearing.

- Low power consumption: The drive draws less than 2 Watts while operating and a mere 4.75 Watts during spin up.

- 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.
