The 1TB WD AV-25 2.5" SATA Internal Hard Drive from WD is engineered specially to offer cool, quiet operation while providing maximum reliability in 24 x 7 environments. 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. 1
It is ideal for video surveillance, DVRs/PVRs, set up boxes, high-end audio systems, karaoke players and digital signage.

      Comments about 1TB WD AV-25 2.5" SATA Internal Hard Drive:

      I purchased this Western Digital, 1.0Tb 5400rpm 2.5" hard drive to put into a HyperDrive COLORSPACE UDMA2 Backup Storage Device Case-Only.

      Prior to installing the hard drive into the UDMA2, I used a SATA/IDE to USB 2.0 adapter to partition the drive using my home computer and run a standard format to ensure the health of the hard drive. The standard format (NTSF) took almost 24 hours to run on this 1.0Tb 5400rpm hard drive.

      I have had no issues using this hard drive.

      Comments about 1TB WD AV-25 2.5" SATA Internal Hard Drive:

      The Western Digital 1TB WD AV-25 2.5" SATA Internal Hard Drive works as advertised.I purchased this internal hard drive to place into a Sanho HyperDrive COLORSPACE UDMA2 Backup Storage Device (SATA Casing Only) and it met Sanho hard drive requirements (especially 5400rpm). Buying this hard drive separately saved me a[$] over purchasing the Sanho 1.0TB HyperDrive COLORSPACE UDMA2 Multimedia Player/Storage Device. I was also not comfortable buying Sanho's complete 1.0Tb HyperDrive not knowing who made the enclosed hard drive, its specifications or reliability.With the HyperDrive on backorder, I used a SATA/IDE to USB adapter to connect the WD drive to my home computer to partition it and run a standard format to ensure the health of the hard drive. The standard format (NTSF) took almost 24 hours to run on this 1Tb 5400rpm hard drive. I also chose this particular drive due to the fact that is has a 16Mb cache compared to others with an 8Mb cache. Overall I believe this Western Digital HD will be a great companion to the HyperDrive.
